Hello I'm working on a 1986 Seaswirl Cuddy 4.3L OMC and stinger 800. I have 4 solenoid 's on this boat do I have too use boat dozens of can I use automotive ones if so what one's to use?
You need to use Marine electronics (solenoids, starters, alternators...) on that I/O motor. They are sealed so they should not spark in the engine compartment and cause a fire or explosion.
