ENGINE BLOCKSix 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.FUEL SYSTEMElectronically 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.LUBRICATION SYSTEM500 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.
