Engine Block

• Four cycle, 3 cylinder, liquid cooled, naturally aspirated, overhead valve diesel.
• Swirl combustion chambers improve fuel efficiency and reduce smoke.
• Glow plugs for quick cold starting.

Cooling System

• Freshwater cooling with siphon break.
• Heat exchanger or keel cooled.
• One-piece heat exchanger, expansion tank and liquid cooled exhaust manifold. Fewer troublesome hoses and gaskets. Cast iron to resist corrosion and electrolysis.
• Heat exchanger cooling is standard. Cupro-nickel, tube-type heat exchanger has removable ends for easy cleaning. Rubber impeller seawater pump of bronze and stainless steel is gear driven; no belt.

Fuel System

• Fuel system is self-venting.
• Injection pump with 5% mechanical governor for close AC frequency control.
• Pintle injectors with replaceable tips.
• Mechanical lift pump with hand primer. No electric pump to fail.
• Large spin-on fuel filter.
• Steel fuel lines.
• Stop solenoid acts directly on the fuel rack eliminating linkage problems.

Intake and Exhaust

• Meets US EPA Tier III emission standards.
• Washable air cleaner.
