I have a 1988 Evinrude 25hp motor that has an issue. The starter is held on by two bolts. One on the front of the casing and one on the right hand side. The bolt hole on the front of the casing is stripped; I have tapped the hole but it will not hold. I have tried to JB weld the bolt in place and I have tried lock tight. Is there anything I can do to get the starter to stay on??? Do I have any other options???
