Northern Lights Marine Generators range in output from 4.5 to 545 kW. Powered by Lugger diesel engines and popular in commercial fishing, yachting and passenger vessel applications, Northern Lights has come to be known for their quality and reliability when it comes to marine generators.

Elements of the Northern Lights generator that make it one of the most reliable, durable and simple to use power solutions on the market:

-High copper content within brushless generator enables motor starting

-Hand-wound, skewed stator makes electricity with symmetrical sine wave for today’s sensitive electrical equipment

-Corrosion-resistant epoxy coating protects against harsh marine conditions

-Designed for quick and easy maintenance

Important for keeping your Northern Lights generator up and running is an understanding of it’s parts, components, accessories, and replacements.

Northern Lights Parts & Accessories

Here is a breakdown of the most common and important parts & accessories for Northern Lights generators:

generator water pumpRaw Water Lugger Pump & Impeller

The Northern Lights Raw Water Pump pushes water through the cooling system of the generator, keeping it below recommended running temperature throughout it’s use. The raw water pump is fitted with a vulcanized rubber impeller. The impeller is a circular rubber component with pallets that facilitate the circulation of water.

Generator Fuel Filter Water SeparatorPrimary Fuel Filter / Water Separator

Fuel filter / water separators extend the life of your generator by removing contaminates in the fuel. Northern Lights fuel filters are designed to protect the engine from damaging particles and water, enhancing overall performance.

marine generator gas water separatorGas Water Separator

Separates exhaust gas and water mixture allowing water to exit under your boat and gasses out at the transom. Reduces exhaust “splashing” noise, allowing more peace and quiet while the marine generator is in use.

Marine Generator Water Lift MufflerWater Lift Muffler

Cools off hot exhaust gasses from your generator, while silencing exhaust noise.

Marine generator dry exhaustExhaust Components

The dry exhaust flex connects your generator’s exhaust system to the engine and reduces vibrations through the dry exhaust. Also allows remote mounting of muffler and compensates for thermal expansion of the exhaust system.

Wet exhaust on keel cooled marine generators use a seawater pump and wet exhaust elbow.

Marine generator exhaust components include:
-Wet mufflers and exhaust gas/water separators.
-Wet exhaust elbows.
-3 and 4 inch dry exhaust elbows with flange.
-Dry exhaust flex couplings
-Dry exhaust mufflers.

Marine Generator Siphon BreakSiphon Break

The siphon break prevents raw water from siphoning back into the engine. It comes standard on 5 and 6 kW Northern Lights generators, but is optional on 8 – 38 kW models. It is intended for wet exhaust systems only.

You’ll need a siphon break if your generator sits so low to the point where cooling water injected into the exhaust is less than a foot above the waterline. Thanks to a natural occurrence known as the siphon effect, water can flow uphill… For more information on the importance of the siphon break in marine generators, see here.

Safety switches for marine generatorsSafety Switches

Safety switches help protect your generator’s vital functions. Choose overspeed, low coolant level, or low oil level to monitor, diagnose, and protect your generator’s key functions.

Marine generator electric fuel pumpElectric Fuel Pump

A Northern Lights electric fuel pump comes in 12V and 24V, and provides design flexibility by allowing the fuel tank and generator to be installed further apart than usual. An electric fuel pump also allows easier fuel system bleeding of the generator.

Power take offPTO – Power Take Off

Available on Northern Lights generators 12kW and up, the front power take-off can provide you with up to 48 Hp, depending on model size and RPM. This will allow you to run accessories at the flip of a switch.

Output alternator for marine generatorHigh-Output Alternator

Increase your battery charging capabilities. Adjustable voltage regulator works with either lead acid or gel cell batteries. Available on larger Northern Lights models.

Sound Enclosure

The sound enclosure creates compact power while reducing sound. Add compound mounts, and reduce noise even further. Sound enclosures work on generator sets up to 30kW, and can be accessed through a steel paddle latch on the service side. Interior latches allow access to non-service side. Northern Lights sound enclosures absorb low-, mid-, and high-frequency noise. Electro-galvanized steel construction and a protective film ensure a long life without scratches/marks/dents.

generator compound mountsPlatform Mounting Kit (Compound Mounts)

Compound mounts completely neutralize noise from base frame vibration, and are corrosion protected for use in marine environments. They are designed to add minimal height to your unit.

You may find it worth your while to learn how to replace filters, and other small parts required in the regular maintenance of your generator. Make sure to follow all safety precautions for marine generators.

Why Northern Lights Generators Beat The Competition

Courtesy of CitimarineStore.com

CitiMarine, one of South Florida’s premier marine service and sales outlets, recently shared these thoughts about Northern Lights quality:

Northern Lights Generators set the bar when it comes to marine generators.

If look up Northern Lights Generators on boating forums, such as The Hull Truth), you’ll see why Northern Lights is ahead of the pack.

Technicians who work on marine diesels and gensets for a living will tell you, Northern Lights are the best by far… simple and very well built.

Northern Lights generators have the best heavily dipped/insulated generator windings, as well as simple electrical wiring/engine harness/controls.

They are lower RPM engines (turn fewer RPMs than Onans or Westerbeke) leading to a longer-life and less problems.

We have received multiple reports of people using NL gensets season after season without so much as a hiccup, as well running the generators for 8,000 hours+ are common.

All that is needed is the occasional changing of oil and filters, and you’ll have a strong, dependable power-source on the waters that will never fail you.

There are several reasons that Northern Lights are the reigning champs in the world of marine generators. Here are some major points:

Much Easier and Convenient To Work On
All the necessary service points for the Northern Lights generator, including filters, fills and drains, are all on one common, easily-accessible side. Besides ease-of-access, this allows you to install it near a wall or bulkhead, in order to save valuable space. On the other hand, other brands often have difficult to access service points, and this dictates where the unit can be placed.

High Torque, Lower RPM Engines
Northern Lights runs at 1800 rpm (60 Hz); this is half the RPMs as most other marine generators. The lower RPMs mean a much quieter operation, and less stress on your engine, leading to a longer life. For instance, in 2,000 hours of operation, the Northern Lights M673LD3will turn 216 million less revolutions, it’s pistons will travel 43,337 fewer miles, and its cylinders will withstand 108 million fewer detonations than most other gensets of the same size…

Superior Engineering, Setup and Manufacturing
High quality components found in Northern Lights generators reduce belts and hoses to a minimum. A single-piece, cast iron heat exchanger, expansion tank and exhaust manifold make the gen set resistant to corrosion and electrolysis, as do the Cupro-nickel heat exchangers. They empty of seawater when not in use, and don’t require zincs.  Most other marine generators have their engine components welded together, which are more likely to fail in a marine environment. Heat exchangers often use aluminum or plastic intakes. Copper heat exchangers and aluminum exhaust manifolds are more prone to corrosion and electrolysis, and need zinc replacement.

Smarter Seawater Pump System
The seawater pumps on a Northern Lights genset are gear driven (no belts), and use mechanical water seals. With other brands, pumps are often difficult to access, belt-driven, and have rubber lip seals, which are prone to deterioration through repeated drying and expansion

DC Logic Design Dependable and Easier to Repair
The simple DC logic design on NL gen sets is reliable, inexpensive and easy to repair. NMEA digital data. Relays are easy to replace when needed. Other generators have electrical systems that use PCBs which are more expensive and less reliable.

Quieter Than All The Competition
In March 2007, an independently certified study commissioned by Victron Energy tested 19 generator sets from different brands, including Westerbeke, Kohler, Onan and Fischer Panda, at 10kW and below.  Of the 19 generator sets, the Northern Lights 9kW was deemed the quietest (lowest sound levels, at less than 65 dBA, followed up by another Northern Lights – the 5kW – at fewer than 66 dBA.

Northern Lights Marine Generators are QuietThe only two Northern Lights tested proved to be the two quietest of the group!

This is Why We’ve Chosen Northern Lights Generators For Our Marine Store

We have the option of selling several top brands of marine generators, but have chosen Northern Lights as our brand of choice for Citimarine Store, for the above reasons, personal experience with the generators, as well as their amazing reputation.

LR Foundation Launches Campaign to Identify Biggest Threats to Safety

The Lloyd’s Register Foundation aims to make a real difference in improving the safety of the critical infrastructure on which modern society relies. It recently launched a consultation to identify the grand challenges to safety at the Lloyd’s Register Foundation International Conference in London.

The consultation to identify the challenges will open today until January 2017, and asks industry, workers and consumers where is safety most compromised either from working with, or arising from poorly functioning infrastructure? Once it has identified these challenges it will ask ‘What can we do about them to make the world a safer place?’.

Dr. Ruth Boumphrey, the Foundation’s Director of Research, said: “Every day billions of people around the world need energy, water, food, transport and other services that make-up society’s critical infrastructure. These infrastructures and their supply chains rely on people to build, operate and maintain them. Our safety is threatened when these infrastructures fail and the safety of those who operate and maintain these infrastructures can be threatened by the environments in which they work .”

Through this consultation the Lloyd’s Register Foundation aims to identify how the safety of critical infrastructures, and the people who build, operate and maintain this infrastructure, is threatened today and into the future.

The Challenge Prize Centre at Nesta, the innovation foundation, will lead the consultation exercise. Constance Agyeman, Senior Programme Manager in The Challenge Prize Centre, Nesta, said: “We are delighted to be working with the Lloyd’s Register Foundation on this unique project. We will be consulting with industry, with those who directly work with critical infrastructure and with the general public to understand these threats to safety.”

The Foundation is inviting input worldwide through the dedicated Safety Grand Challenges website www.safety.challenges.org. The findings of the consultation will be published by the Foundation in 2017 in a foresight review that will outline the key safety issues and suggest types of innovation and initiatives that could address these challenges. The Foundation will promote this work through a series of programs under the Safety Grand Challenges campaign.

The campaign’s pilot program will address the safety issues surrounding moving people from one ship to another: ‘ship-to-ship transfer’. Leading this work, the Royal College of Art (RCA) has challenged its postgraduate design students to find innovative interventions to a hazardous activity – one commonly performed around the globe every day. Professor Ashley Hall, Professor of Design Innovation at the RCA said ‘‘The Foundation’s Grand Challenge is a great platform to explore ways that design-led innovation can bring new thinking into saving lives at sea. Ship-to-ship transfers – where a pilot boards a larger vessel in order to guide it into and out of port – is a high-risk activity. Casualties and fatalities are common and often under-reported. Good design puts the user at the forefront of any activity; it combines physical and psychological insights to generate solutions using appropriate technology. Design is a highly tangible activity and we will be designing and building a series of prototypes that to be exhibited in early 2017.”

Virgin Islands Winter Escape

Tom Richardson

US Virgin Islands Aerial Photo

Steve Simonsen Photography

As our 35-foot center-console rode the big Caribbean swells, I couldn’t believe I had actually pulled off my escape from the snowiest winter ever recorded in New England. Just two days earlier, on February 15, I had been gazing at the barren, wind-blasted tundra purported to be Boston’s Logan Airport, where the temperature was so cold it had caused the tow bar of our plane’s pushback tractor to snap like a strand of uncooked spaghetti. As the crew waited for a replacement tractor to arrive, an entire jetload of dejected passengers was thinking the same thing: We shall never leave this cursed land!

Yet here I was, with friend Jonathan Craig, heading toward bluewater adventure off St. Thomas and St. John in the U.S. Virgin Islands. The six- to eight-foot seas heaving beneath the hull were a parting shot from the big storms that had pummeled my home coast nearly every week since mid-January, but we didn’t mind. For once, it wasn’t snowing.

“This has been a particularly rough winter for us too,” acknowledged Capt. Jonathan Gatcliffe, who, along with mates Tyler Maltby and Glenn Charlett of Double Header Sportfishing, had picked us up in St. John’s Cruz Bay. Like ripples expanding in a pond, swells generated by winter nor’easters in New England often extend to the Caribbean, creating heavy surf along the islands’ north-facing shores and stirring up the inshore waters. Fortunately for Virgin Islands fishermen and visiting anglers, there are plenty of options, especially if you have a big center-console at your disposal.

Live-chum the Virgin Islands with pilchards.

Tom Richardson

While many USVI captains choose to troll, live-chumming with pilchards can be more productive.

Pilchard Power

Despite the heavy seas, our destination was the legendary North Drop, offshore grounds made famous by big-game pioneer Johnny Harms in the 1960s. Fishing out of St. Thomas, Harms discovered that this abrupt curve in the continental shelf 20 miles north of the island, where the depth plunges from 200 to more than 2,000 feet in less than a quarter-mile, produced immense upwellings that attracted baitfish and large predators. Happily, it still does.

Unlike the traditional method of trolling for offshore species, the Double Header crew prefers live-chumming, a technique Gatcliffe imported from his home island of Trinidad. Gathering the 500 pilchards needed before each trip is a lot more work than dragging lures, but it usually pays quick dividends, as we discovered immediately upon pulling up to a lobster-pot buoy that had been set near the edge of the shelf drop-off.

The buoy was adorned with several long stalks of bamboo, and Gatcliffe explained that the local lobstermen often use these homemade fish-aggregating devices (FADs) to bag a few bonus “market fish” while hauling their traps.

Virgin Islands FAD

Tom Richardson

A buoy marks this homemade fish-attracting device made with bamboo.

Fabulous FADs

As Gatcliffe set up a drift past the bamboo FAD, Maltby scooped a half-dozen pilchards from the transom livewell and scattered them over the surrounding water to sound the dinner bell. Meanwhile Charlett cast out a pair of free-lined baits within 20 feet of the FAD, on medium spinning outfits spooled with 20-pound-test mono. Seconds later, line was peeling off one of the reels and Craig was fighting our first fish of the day.

One of the many benefits of live-chumming is that it allows for the use of relatively light gear, and Craig had his hands full with what turned out to be a 30-pound wahoo. The standard gear employed by the Double Header crew when targeting both wahoo and mahimahi consists of Offshore Angler Frigate spinning reels and 7-foot Ocean Master rods rated for 20-pound line. The reels are loaded with 50-pound-test braid backing, followed by a top shot of 20-pound-test mono. When toothy wahoo arrive, the crew adds 2 feet of 40-pound-test single-strand wire ahead of a 6/0 Owner circle hook. The wire is connected to the mono via a small barrel swivel.

Wahoo are a headliner species in the Virgin Islands during winter and early spring. Most weigh 30 to 50 pounds, although fish up to 100 pounds can be found. (Gatcliffe’s personal best is a 110-pounder.) Prime time is November and December, but good numbers of fish hang around through March. Indeed, Gatcliffe and Maltby have even caught them over the nearshore reefs in depths of 100 to 150 feet when bluewater pushes in close to the islands.

If live bait proves scarce or the FADs aren’t holding fish, Gatcliffe and Maltby often troll for wahoo using high-speed jet heads, Halco Tremblers, and deep lures fished behind Z-Wings around weed lines, rips and birds. The technique can be effective; however, nothing beats the excitement of using live chum.

When live bait proves scarce and the FADs don’t produce, USVI captains troll for wahoo.

Wahoo gaffed in U.S. Virgin Islands

Tom Richardson

Prime wahoo time starts in late fall and runs through winter. The fish average 30 to 50 pounds but can top out over 100.

Mahi Mayhem

With a fine ’hoo on ice, we picked up and ran to another pot buoy. This time we uncovered a pack of aggressive mahi that ambushed our pilchards almost before they hit the water. For several minutes, pandemonium erupted as the frenetic fish crashed baits, leaped around the boat, and flopped about the deck. When the dust settled, we had landed about a dozen fish from 8 to 15 pounds, some of which were herded into the fish box and invited to dinner that evening.

Live-chumming for mahi is fast-paced, high-drama fishing and allows the angler to cast artificials. Topwaters, epoxy jigs, metal spoons and a variety of flashy flies all work once the fish have been whipped into a frenzy by the live bait. Like mahi pretty much everywhere, these fish become hard to catch once a few are pulled from the school, so when the action dies, it’s best to try another spot.

Mahi are year-round residents of the islands. They can be found along both the North Drop and the less famous (but no less productive) South Drop — the steep shelf edge 10 miles south of St. John — throughout the winter, as well as over the nearshore reefs at times. However, the biggest fish, up to 60 pounds, are typically caught in May and June.

Mahi dolphinfish thrive in Virgin Islands water

Pat Ford

School-size mahi can be found year-round off the USVI’s North and South drops, and around nearshore reefs. Larger fish — to 60 pounds — arrive in May and June.

Those Summer Blues

Spring also happens to mark the start of marlin season. Blues begin to show along the South Drop in April, whereas the prime bite along the North Drop takes place from June through September, with the week after the August full moon being most productive. Of course, a few marlin are always present offshore, and sometimes make unexpected appearances during winter and spring trips.

Following our initial flurry of action with the mahi, we leapfrogged from buoy to buoy for the next hour, bailing fish at nearly every stop. If the mahi failed to show right away, Maltby would send down a live bait on a downrigger set at 50 feet and slow-troll it around the buoy.

This technique is also a great way to target yellowfin and blackfin tuna around the buoys, although the downrigger bait is usually set a bit deeper for the tuna. Maltby explained that both species are taken throughout the year, although their presence is somewhat unpredictable. “November 2014 was incredible, simply off the charts,” he said. “However, April and May were the hot months in 2013. You just never know with tuna.”

Since the tuna are bigger and stronger than mahi, the Double Header crew targets them using live pilchards fished on 50-pound stand-up gear. They pair 5-foot-9-inch Connley short-butt rods with Shimano TLD and Tiagra 50 reels, backed with 80-pound braid and topped with 60- to 80-pound mono. The rigs are finished with 6 feet of 60- to 80-pound fluorocarbon leader and a 9/0 Mustad circle hook.

While the yellowfin, which average 40 pounds, could be taken on lighter tackle, the heavier gear allows anglers to horse the fish to the boat before sharks can home in on them.

Visiting anglers can stay on St. Thomas or St. John, which is accessible by ferry from Charlotte Amalie and Red Hook harbors.

Island Guide

The U.S. Virgin Islands include three islands: St. Thomas, St. John and St. Croix. The former two represent a separate fishery from that off St. Croix; they’re 50 miles away and closer to the productive waters of the North and South drops that mark the edge of the continental shelf.

Visiting anglers fly into St. Thomas and can stay either on St. Thomas or on neighboring St. John, just 3 miles east and accessible by ferry ($14 round-trip) from either Charlotte Amalie or Red Hook harbors, where the majority of charter boats are based.

Double Header Sportfishing is based in Red Hook, on the east end of St. Thomas, but will readily pick up charters in Cruz Bay on nearby St. John. Captains Jonathan Gatcliffe and Tyler Maltby maintain a pair of 35-foot center-consoles and a 42-foot sport-fisherman that allow them to target nearshore and offshore species.

They run half-day, three-quarter-day and full-day trips for everything from blue marlin and tuna to kingfish and snapper, and can fish both the North and South drops. Rates range from $600 for a half-day trip aboard a 35-foot center-console to $1,400 for a 10-hour marlin trip aboard a 40-foot sport-fisher. Guests may request up to 20 pounds of fish to keep per charter (30 pounds on a full day), which the captain will fillet. The remainder of the fish stays with the boat. Contact Double Header Charters for more information at 340-777-7317 (doubleheadersportfishing.net).

Accommodations on St. Thomas and St. John include everything from luxury resorts to campgrounds. A variety of rental villas — ranging widely in price from about $1,500 to $6,000 per week — are also available through Caribbean Villas (caribbeanvillas.com). Hotel options on St. John include the Westin (866-716-8108; westinresortstjohn.com) and the Caneel Bay Resort (340-776-6111; caneelbay.com). On St. Thomas, try Marriott’s Frenchman’s Cove, Secret Harbour Beach Resort and the Ritz-Carlton.

Travel to the Virgin Islands from the East Coast is remarkably easy. Jet Blue offers direct flights to St. Thomas from Boston, and American, Delta and United also fly to St. Thomas via a variety of connecting cities. For more USVI information, visit vinow.com.

Making The Right Choice for Onboard Comfort

It’s a story as old as manned sea-craft itself – how do you provide climate control that is suitable for the entire crew? Crew comfort is a key consideration for retention and regulation. Your crew works hard, but disputes about the amount of air conditioning or heating, and when and where to turn it on, have been inevitable.

The Marine Climate Control Experts at Technicold recommend individual compartment controls.  This will maximizes crew comfort while minimizing management headaches.

A world-class line of chilled water and direct-expansion air handlers will be designed to fit easily in almost any berth or compartment. When specking climate control, look for features including vertical assembly and rotatable insulated blowers.

There are other ways to enhance onboard comfort and safety. Electric heat strips and immersion heaters provide cold environment solutions. Install a dash heater in the pilot house to defrost the window, enhancing safety. Anti-bacterial UV lamps eliminate odors and improve air quality.

And if that still isn’t enough to keep the peace on board, look for locking control panels – just set it and forget it.

Technicold Condensing Coils – How a Small Detail Makes a Huge Impact

In the world of vessel design, climate control is an important factor. But one of the most critical factors in the quality of the air conditioning system is one that is easy to overlook – the condenser coil.

Many manufacturers use copper coils that are subject to failure from sitting coolant and corrosion. The Marine Climate Experts at Technicold have a better way.

condensor coil

Technicold uses only large, single pass fluted coaxial cupronickel counter-flow condensing coils.   That is a lot of features packed into a small component, so let’s break it down:

  • Large coil size ensures efficient coolant delivery.
  • The fluted design prevents sitting coolant and water that can lead to corrosion.
  • Cupornickel is a robust alloy that is known for its resistance to oxidation.
  • The counter flow condenser allows low sea water velocity for even condensing.

This level of attention is only one of many examples of the thoughtful engineering that goes into every Technicold product. Made specifically for the harsh marine environment, Technicold chilled water air conditioning systems feature 316L grade stainless steel hardware and low-condensation design to ensure the best long-term value in the marine industry.
