KEY FEATURES
Indirect Cooling: Uses internal freshwater cooled by raw seawater via a heat exchanger to prevent salt buildup inside the engine block.
Compact Footprint: Engineered with small dimensions to fit tightly into narrow sailboat and small craft engine bays.
Mechanical Simplicity: Relies on high compression and a swirl-type pre-combustion chamber rather than glow plugs for reliable starting.
Optimal Torque: Features a standard reduction gear ratio (such as 2.62:1) designed to deliver strong propeller torque in displacement hulls.
