2 weeks ago i broke a bolt on the starter. i replaced both bolts and have went out 5 or 6 times since then with no problems. now today i took it out and started fine at the dock ran it all day till we decided to float for a while and then when i went to start it, it would start to start fine and then make a load grinding sound and never actualy start. after trying this acouple times it finaly started squeeled for a minute and was fine so i got the boat in of the water. when i got the boat home i checked the starter bolts and one of them was a little loose. is this what is causing that? any ideas would be great!
