There's a salvage yard in KC, one of the midwests biggest, I can't recall the name right now. On the flip side, at a minimum check your lower unit in the fall for water in the oil. It's actually best to just change it for reassurance. Also, when finished fishing drop your motor all the way down at the ramp while you strap down and get ready for the road. This will drain your motor of water. Also, to prevent other damages store the motor down if you store outside to prevent water build up in the hub. I feel your pain and was "lucky" to learn these lessons at a friends expense, he burnt his motor completely up because of the reasons I stated.
