VETUS M2.18 – Marine Diesel Engine 16 HP

VETUS M2.18 16 HP – Compact Twin-Cylinder Marine Diesel

Minimizing weight without sacrificing charging capacity is the primary engineering achievement of the VETUS M2.18. Delivering 16 HP at 3600 RPM, this 2-cylinder engine is built on a reliable Mitsubishi block and features VETUS’s signature water-cooled aluminum top cover to reduce engine room temperatures and noise. For American owners of pocket cruisers and day-sailers, the M2.18 provides a refined auxiliary power source that excels in fuel economy while offering a high-output 75A alternator—rare in this power class—to keep USA house battery banks fully charged for navigation and LED lighting.

Meeting strict EPA Tier 3 emission standards, the M2.18 is designed for easy maintenance in the tight engine bays of 20-25 foot American sailboats. The freshwater cooling system and saltwater-resistant heat exchanger provide a critical defense against internal corrosion in the high-salinity waters of the Atlantic and Pacific coasts. Its lightweight construction (only 216 lbs) ensures minimal impact on vessel trim, providing USA sailors with a dependable, smooth-running partner for harbor maneuvers and coastal transits.
