Recently bought and replaced the lower end unit. Ran offshore 2 times and put roughly 20 hours on her, ran better than ever. Was putting the boat on the trailer, slipped into netral and then when I put it in reverse to straighten it out, jumped into forward gear and slammed into dock, put it ibto netral stayed going forward at idle speed. Ended up turning key off and killing batteries to shut it down. Very dangerous. The worst part about it, once I wenched it on the trailer and had it hooked up. I started it back up and tried forward, neutral, and reverse and all the gears seemed to be working fine. Anyone have any suggestions to what my problem may be. I don't want to evrn drop it in and mess with it until I am confident it wont do this again. Please help-Mini Season starts soon and I need to get it straight, cant be messing around with this problem with people in the water. I thank ya in advance.
