Hi - I have a 1985 Mercruiser and I think the solenoid is bad. When i try to start the engine, I get a whining , whirring sound. I was told the "bandex" was not releasing so the starter wasn't engaging the engine. I have 2 questions: 1-does this sound correct, and is there something I can do to fix it without replacing it? Question 2 is that if I have to replace the solenoid, I have been told that since my engine is basically a Chevy engine so I should be able to find the parts at an auto store. I have the part numbers for the solenoid, but it is a mercury part number. Is there a way to find out the Chevy part number so if I go to an Autozone I can give them the right number?

Thanks for the hlep!

Take the starter off, take it apart and clean up everything. If you aren't comfortable with doing this take it to a starter shop. Rust on the plunger and/or gunk on the shaft can keep the starter from engaging. You may need parts.

Sounds as though the bendix is not operating. The solenoid typically gives you a clicking noise when failing. Also the autozone parts are not for marine use as they are not sealed/sparkproof.
