M1306 Series: 355-400/ 300-400 kW

Prime kW ratings for 3Ø at 0.8 power factor. Consult factory for deration factors.
Net flywheel hp rating for fully equipped engine at rated speed under SAE J816b.
Based on prime kW rating at 1800 and 1500 RPM. Fuel rate may vary depending on operating conditions.
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.
Dimensions are subject to change without notice, they are not intended for installations. Contact a factory representative for the current installation data.

Six cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesels based on heavy-duty industrial engine blocks.
Balanced alloy steel crankshaft with induction hardened journals and rolled fillets.
Replaceable valve seats and guides.
Strong three ring steel pistons for long-life reliability.
Gear-driven seawater pump.
Drive belt powers the alternator and freshwater pump.
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.

500 hour oil change interval when fuel and oil requirements are met.
Positive displacement gear-type oil pump.
Full flow, spin-on oil ﬁlter.
Centrifugal oil cleaner reduces piston crown temperature for longer life.
Freshwater, plate-type, full flow oil cooler reduces heat and thermal breakdown of lube oil.
Large capacity oil pan.
Floating, cast aluminum, rocker cover traps valve noise and is a closed loop crankcase vent.
Lube oil drain for easy changes.

Freshwater cooling system with twin thermostats for quicker warm-ups.
Heat exchanger cooling includes: Gear driven, flexible impeller seawater pump. Easy to clean, tube-type cupro-nickel heat exchanger.
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.
Zinc anode electrolysis protection.

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.

Direct coupled, single bearing, 12 lead, reconnectable AC generator. Maintenance free brushless design.
Generators meet or exceed class society standards. All have class H insulation, accessible diodes, oversized ball bearings, marine grade shafts and conservative 95°/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.
