Standard Features

Long lasting 3000-rpm performance...

Lightweight and CompactDesigned by Westerbeke, pioneers in lightweightmarine diesel engines, the 35E Three is a compactthree-cylinder engine perfect for difficult installations.The 35E Three provides a power to weight ratio to beenvied while requiring modest engine room space.

Powerful, Reliable and QuietThe 35E Three is rated at a low 3000-rpm for longerengine life. It is designed and built using experiencegained in supplying over 1,100 whaleboat engines tothe United States Navy. The 80.43 cubic inchdisplacement of the 35E Three delivers reliablepower without sacrificing smooth and quiet opera-tion. For enhanced quiet performance, this enginealso has tuned air intake silencer.

Easy Operation and MaintenanceTo minimize engine maintenance, the 35E Three isfresh water cooled and equipped with a simplecontrol system. Easy access to all servicing pointsand a self-bleeding fuel system allow easyinstallation and routine maintenance.

Full Engine Instrumentation OptionWesterbeke offers an optional admiral panel. Theadmiral panel includes, tachometer, hour meter,voltmeter, water temperature and oil pressure gauge.Westerbeke also offers an optional captain panelwith tachometer, hour meter, and warning lights.
