Volvo Penta D12 715

The Volvo Penta inboard diesel D12-715 is offered in a high power 715 hp (526 kW). It offers excellent performance and a pleasant cruising.

The boat engine is a further development of the successful and well-proven high pressure unit-injected and 4 valves per cylinder D12 marine engine. Its go and electronically controlled wastegate turbo, a newly designed heat exchanger for reduced charge-air-cooling temperature in combination with a new injection system, and a new Engine Management System (EMS-2) to further improve performance and drivability. This makes the D12-715 able to meet future stringent emission requirements.

A rigid in-line six cylinder block engine with ladder frame and vibration dampers on the camshaft results in a smooth running engine for high onboard comfort.
