Hey All, I have a 1994 Proline with a 5.7 L Mercruiser Bravo stern drive. The engine blew 2 years ago so I pulled it and had it completely redone. Now, when I install the starter ( 7 starters later) the engine will turn over for a few minutes with now problems then there is a BAD grinding sound. So once it starts doing that I stop trying to start it and I pull the starter again and the starter drive is always broke. When I put the starter on the vice and get the jumper cables and make the starter kick in and run, it runs but when you put a screw driver on the spines to the gear you will see that the drive itself is stripped out. This is the 7th starter I have gone through with the same outcome....any help would be great!!
