Expect the Best of the Best.

Indy-winning engineering and outstanding performance combine to power the Ilmor Inboard Marine series. Ideal for recreational boating of all kinds, these engines are built to the same exacting engineering standards as our world-renowned race engines. They deliver the highest levels of performance AND reliability, so you spend less time in the service center and more time on the water.

Ilmor's Inboard Marine engines are available for both fresh and salt water (Ocean Performance Series) in displacements of 5.7L, 6.0L, and 6.2L (7.4L available in open-cooled only).


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. Fuses, relays, and circuit breakers are housed in a compact and centrally located fuse box, with easily identifiable fuses and a 50-amp reset-able circuit breaker to prevent temporary problems and ensure an enjoyable day of boating.
