I have the same problem, went through 2 starters in 2 weeks, the starter would turn over but it sounded like the teeth were gone, made a sound like when you try to start ur car with the engine already running, even with the new starter it sounds "tinny" when turning over, turns out the flywheel was bad, i'm not sure if this is the problem you have, mine is also the volvo 3.0 I/O

Starter problems by: jerry
I am on my 5th. starter and no one can give me a answer.It's on my boat that leaves us high and dry all the time. It will start fine when we leave the dock,but if we stop someplace and try to start it to go home the starter is dead. It's on a volvo penta motor. Someone must no the answer. Please help.Thanks.
