I just pulled my starter to have a look at my flywheel.. Its worn very badly and wont start. Im curious as to what a ring gear replacement will cost. Its a mercruiser 5.7L. I know the engine will have to be pulled. What should I expect to pay for this repair, Im sure I could get all kinds of prices from low to high... Just curious as to what the average repair cost should be.. Can anyone tell me what I should expect?
