I have a 1994 Volvo Penta 4 cyl 3.0 L engine. I recently got a loud grinding noise when attempting to start the engine. I gave it about 4 tries but the engine didn't start, the week before I was able to start the engine right away. Although it did give problems after I stop to refuel and attempted to start it. I got a similar noise but it starter after several tries. I am attempting to remove the starter but I am unable to remove one of the bolts. I can't get anything in there!! It is wedged in a corner. Any tricks on how to get to the stupid bolt? I could grind the plate, but I never done that before and I don't have the tools (suggestions on what to buy/rent.) Grinding seems like an option if I had the right tool, but I am afraid I could damage something.
