I had a problem like this with my old one. Mine was a simple fix. The selector rod has a trend of popping outa the plastic selector switch. I set my TM out like if I would be using it while on the trailer. Removed the 6 screws from the bottom of head and remove the top cover. The black handle will have a rod that comes from the center that connects to the electronic selector. There is a horseshoe metal plate in there that goes a certain way. Just watch for that on the get go, so if it falls out; you know were it goes back. I think its from hard bouncing across the water.
