To repair or not repair?
If you didn't, I would like to recommend taking it to the Boat Doc in Lomira. He is the best Mercury dealer in Wisconsin. Fair prices, honest, plus it will be fixed right the first time. I know it may be a little drive for you, but it will be well worth your effort.
I am not going to air out my whole experience with them, but I will not give them any type of positive feedback for any perspective customers for the future. I will just leave it at that. Buyer beware!
