btilley, im having this same exact problem with mine right now. exept that it has never done it first thing right off the trailer. its after i run it, fish for a few hours then crank it again. if i idle a while then go to take off i will have an alarm sound. like the over heat alarm. ill kill it then turn key back on and itll be fine. id sure like to know what the problem is if you figure yours out because i dang sure cant figure mine. by the way, looking at your avatar btilley, it looks as though we have the same exact boat and motor, color and all.
