Marine Engines 42HPE

Inboard Marine Engine

Models: 42HPE 350 - 42HPE 330 - 42HPE 300 - 42HPE 280 - 42HPE 250 - 42HPE 150

The 42HPE engine was developed on a VM engine basis.

The 42HPE Inboard Marine Engine has these features:

4 stroke turbocharged and aftercooled, direct injection diesel engine with electronically controlled common rail injection.
Cooling controlled by separa- te fresh and salt water circuits, with extractable hoses for easy maintenance.
Lube oil, water and air circuits designed to reduce external flexible pipes to a minimum to reduce loss of liquids in the bilge.
Auxiliary devices driven by Poly-V belt to ensure excellent power transfer and long life compared to traditional versions
Electrical circuit protected by reactivateable valves.
