3YM20

YM Series NEW 3YM20 (21HP/15.3kW)
Yanmar diesel engines are specially developed to serve marine applications, giving customers the most reliable propulsion systems available on the market.

Powerful and Lightweight
The all-new cylinder block design makes Yanmar engines the lightest in their class. The big displacement provides even higher torque. This makes the engine not only more powerful, but also gives them the best power-to-weight ratio available.

Efficient
The all-new ML Fuel Injection Pump provides you with the optimized combustion and the best fuel economy ever. It ensures easy cruising and a minimum of engine drag.

Compact Dimensions
Yanmar engines provide the smallest dimensions in their class. This allows more room in the engine compartment during maintenance, ensures easy installation when repowering and results in faster boat speeds.

Whisper Quiet & Low Vibration
The large intake silencer prevents higher noise vibration from spreading around, giving you a whisper quite operation. THis ensures you a more pleasant and rewarding boating experience. The super flexible engine mounts and cylinder block with extra stiffness keep vibrations to an absolute minimum. Offering you the smoothest ride possible.

More Torque
The extraordinary torque of Yanmar diesels provides biting power, even at low engine speeds. Torque achievements are facilitated by high displacement from lightweight, compact blocks and advanced engineering.

Easy Maintenance
All check and maintenance points on the engine (oil dipstick, oil filter fuel filter and water pump) are concentrated at the front of the engine on the same side. This makes all engine checks and maintenance quick and simple, providing you more time to enjoy your boating.

Cleaner with No Visible Smoke
The close blow-by system ensures that carter ventilation is returned to the engine, avoiding any harmful discharges into the surrounding air. This not only makes your engine compartment cleaner and safer, it also reduces the impact on the environment.

User Friendly
The stop solenoid connects to an easy legible user panel for your convenience. This offers you a reference panel with a keystart, digital rpm counter, water temperature gauge and oil pressure alarm buzzer/light.

Easy Start & Powerful Electrical Systems
The standard 60 Amps alternator provides powerful primary electricity generation, giving you a sure power supply.
