COMPACT POWER, PROVEN RELIABILITY

The Yanmar 1GM10 marine diesel engine is engineered for sailors and operators who value dependable auxiliary power in a compact, efficient package. Designed for small yachts and light displacement vessels, it delivers consistent performance where reliability and simplicity are non-negotiable.

EFFICIENT SINGLE-CYLINDER PERFORMANCE

With a naturally aspirated, four-stroke single-cylinder configuration, the 1GM10 provides smooth, predictable power delivery. Its torque characteristics are well suited to auxiliary propulsion, offering confident manoeuvring and steady cruising performance without unnecessary complexity.

BUILT FOR THE MARINE ENVIRONMENT

Purpose-designed for marine use, the 1GM10 features direct seawater cooling and corrosion-resistant components to withstand harsh saltwater conditions. The robust mechanical fuel system prioritises reliability and long service life, even in demanding coastal and offshore applications.

QUIET, CONTROLLED OPERATION

Carefully balanced internal components and refined combustion contribute to low vibration and controlled noise levels. The result is a more comfortable onboard experience, particularly important on smaller sailing yachts where engine noise is immediately noticeable.

STRAIGHTFORWARD INSTALLATION

The engine’s compact footprint and low overall weight simplify installation in confined engine bays. Available in shaft drive or saildrive configurations, the 1GM10 integrates easily into both new builds and repower projects, offering flexibility across a wide range of vessel layouts.

ENGINEERED FOR LONG-TERM OWNERSHIP

Durable construction, proven marine diesel engineering and conservative operating characteristics ensure the 1GM10 delivers reliable service over the long term. It is an engine designed to start when needed, perform consistently, and support years of confident operation.
