Question
starter

I have a 1979 Mercruiser and the starter clicks. Any idea on how I can check the starter or get the starter to turn over? It was working fine until last week.

Submitted by: Les
Answer

First make sure you have a fully charged battery and all cables are clean and tight. If you have good voltage to the starter, try tapping the starter case with a hammer. If that doesn’t free things up, you will need to remove the starter.
