  FEATURES

Designed With You in Mind

With a high-mount alternator and starter motor, and a conveniently positioned remote-mount oil filter with courtesy tray, our Inboard Marine engines are easy to service. Our custom electronics wiring harness is designed to minimize excess wiring and make it easy to identify connections. Use of an ePDM (Electronic Power Distribution Module) system eliminates the need for caring fuses and helps ensure a great day of boating by making the reset of a blown circuit simple and intuitive.
