I follow a few marine engine forums, but this one is the only one where solenoid is (usually) spelled correctly. Soleniod, selinoid, soliniod, solinoid, etc.

My guess is that it wasn't the solenoid in the first place, but a starter that needs to be rebuilt. Or you can purchase a rebuilt one for about $300 while you are having yours rebuilt (about $150). ...
