I don't have any idea how to fix the motor but if you can edit your thread title to something about a trolling motor problem, you will get more help. You have a very specific need there. Best of luck on it. BTW, the problem with the 'runaway' boat with no captain is a lesson for all, that could've been even more scary if she had not been able to get it cranked. So, a rope might be a better solution. Glad she got it cranked.
