Mercury Mercruiser Relay

Relay Mercury Mercruiser

Relay (also known as solenoid ) used for both the starter and trim pump. Fits many MerCruiser gasoline engines , 2.0 liter diesel engines , and Alpha One and Bravo drives . Also fits some Mercury 250/300XS (DFI Optimax) engines, as well as many older 2-stroke carbureted engines and some EFI models (175-200 hp) .

If the starter or trim pump does not work, this relay could be a possible cause of the problem.

Tip: Check the OEM number of your existing relay before ordering. The number may be on the back of the relay, in which case the relay must be removed for inspection.
