LP Series 191–233kW (260–315HP) In-line six-cylinder Yanmar diesels, including sterndrive models.

The water-cooled turbo with wastegate really makes things happen when the throttle lever is pushed forward hard. LP Series 6LPAM-STP (315HP/232kW) Four valves for each of the six cylinders on this high performing diesel engine. Turbocharged, aftercooled and direct injection. Supplied as bob-tail unit so that you can choose your transmission type.
