Hey everyone im new to this site. Recentely just had a whole new 1100 motor put into my ultra 130 di becuase the other one seized. Motor was put in was breaking it in for about a half hour and all of a sudden the shaft came loose from the motor. I loosed the motor mounts and pulled the engine back and bit went out again and same problem happened within two seconds the shaft came loose. Any expertise would be greatly appreciated on what to do!
