mercury starter solenoid installations manual


Mercury does not offer an installation manual for starter solenoids. If you need help with wiring, then you would probably need a wiring diagram from a service manual.

Replaced the original solenoid with the exact replacement from Crowley Marine.


Very good experience. Parts were delivered on time and with the right part numbers that I ordered. Your online schematics makes it easy to pick out the parts that I needed.
