Notes

  1. Prime kW ratings for 3Ø at 0.8 power factor. Consult factory for deration factors.
  2. Net flywheel hp rating for fully equipped engine at rated speed under SAE J816b.
  3. Based on prime kW rating at 1800 and 1500 RPM. Fuel rate may vary depending on operating conditions.
  4. Data for units with hydrolastic mounts, heat exchanger cooling and 3 phase generator ends. Dimensions and weight are affected by optional equipment, AC output, phase, exhaust and cooling configuration.
  5. Consult factory for data on enclosures for sets with InSep.

Dimensions and weights are subject to change without notice, they are not intended for installations.

Features + Benefits

• V-12 cylinder, four cycle, liquid cooled, overhead valve, marine diesels based on heavy-duty industrial engine blocks
• Balanced alloy steel and induction hardened crankshaft
• Replaceable valve seats and guides
• Strong three ring steel pistons for long-life reliability
• Gear-driven seawater pump and freshwater pump
• Drive belt powers the alternator
• Replaceable, strength-optimized wet cylinder liners for long life and low rebuild costs

• Electronically controlled high-pressure fuel injection system provides individual control in each cylinder for low exhaust emissions and superior fuel economy.
• High torque at low revolutions (1800 or 1500 rpm)
• Full flow spin-on duplex elements
• Gear driven fuel transfer pump with primer
• Flexible fuel lines routed to fuel manifold on base frame for easy installation of vessel’s hard piping

• 600-hour oil change interval when fuel and oil requirements are met
• Force feed lubricating by gear oil pump
• Full flow, spin-on oil filter
• Oil cleaner is based on impactor technology to extend oil change intervals
• Freshwater, plate-type, full flow oil cooler reduces heat and thermal breakdown of lube oil
• Large capacity oil pan

• Dry air filter silences intake noise
• Aftercooler with marine quality, cupro-nickel, single pass element
• Turbocharged for increased output

• Freshwater cooling system with three thermostats for quicker warm-ups
• Heat exchanger cooling includes: Gear driven, flexible impeller seawater pump.
• Cast aluminum expansion tank with brass filler neck. Cast-iron exhaust manifold has single pass freshwater flow for even temperature control, fast warm-up and no hot spots
• Titanium plate heat exchanger – no zinc anode protection necessary

• Engine supplies SAE J1939 data stream through a CAN bus plug for optional
engine monitor
• Negative ground, 24-volt DC system with circuit breaker, starter motor and battery
charging alternator with regulator. Isolated ground optional
• Standard digital controller displays engine hours, coolant temperature, oil pressure,
DC voltage, and includes start-stop controls. Increased ease of paralleling through
controller
• Engine and panel are pre-wired with terminal strips
• Low oil pressure and high coolant temperature safety shutdown system included
in controller

accessible diodes, oversized ball bearings, marine grade shafts and conservative
90°/50° heat rise ratings
• Engines and generators are torsionally matched for long life
• Automatic voltage regulator gives fast response to electrical load changes. Voltage
is regulated to ±0.5% (one half of one percent) over the entire range from no load
to full load

• Isochronous electronic governor for 0% AC frequency droop
• PMG (permanent magnet generator) to power AVR for 300% short circuit capability
for “classed” vessels

• Standard hydrolastic mounts isolate 98% of hull vibration
• Welded steel base frame. Easy to mount and keep clean
• Belt guard protects operator even on sets in sound enclosures
• Sparkling white IMRON® polyurethane paint for protection and visibility
• Operator’s and parts manuals

• IMO Tier 2 and Tier 3 compliant
• Available certification from CCS upon request
