Yanmar 4LH-DTE 170hp Marine Diesel Engine

Yanmar 4LH-DTE 170hp 4 Cylinder Turbo Intercooled Heat Exchanger Cooled Marine Diesel Engine.

Currently available as a bobtail engine in full running order.

This engine was taken as a part exchange against a more powerful Yanmar and is reported to have run just over 750hrs from new.

Originally fitted in a Sea Ray motor cruiser so has not been used commercially.

The original instrumentation remained on the boat to be used with the new engine but we have a suitable Yanmar control panel & loom that will be included with the engine.
