Vetus M2.05 Marine Engine

The Vetus M2.05 marine engine is a compact and reliable diesel propulsion system designed for small recreational vessels, tenders, and auxiliary sailboats requiring dependable power, fuel efficiency, and long service life. Part of Vetus’ proven M-series, the M2.05 combines robust mechanical construction with marine-specific engineering to deliver smooth operation and durable performance.

At its core, the M2.05 features a 2-cylinder, 4-stroke diesel engine with a displacement of approximately 0.5 liters. Despite its small size, it delivers around 8 to 10 horsepower, offering sufficient torque for displacement hulls and small auxiliary sailboat propulsion. The naturally aspirated design and precise fuel injection provide efficient combustion, consistent low-RPM torque, and smooth, reliable operation, making it ideal for auxiliary or short-range propulsion tasks.

The engine is adapted for marine use with a freshwater cooling system and heat exchanger, protecting internal components from corrosion while maintaining stable operating temperatures in both saltwater and freshwater environments. Its compact, lightweight construction allows easy installation in tight engine compartments, making it ideal for small boats, tenders, and repower projects.

Durability and serviceability are key advantages of the M2.05. Heavy-duty components and robust construction ensure reliable operation during continuous use. Service points are strategically placed for convenient onboard maintenance, and the engine’s simple mechanical design reduces electronic complexity, simplifying troubleshooting and routine servicing. The M2.05 can be paired with compatible marine transmissions or saildrives, providing flexibility for various propulsion setups.

Ideal for small sailboats, tenders, and lightweight auxiliary vessels, the Vetus M2.05 Marine Engine provides a reliable combination of compact size, fuel efficiency, smooth operation, and long-term durability, offering dependable and efficient auxiliary propulsion for a wide range of recreational and light commercial marine applications.
