Re: key on tilt goes up???
I think the reason Silvertip is recommending it, is the control and the trim controls are specific to the type of motor, and they will have a better response. We would be able to give generic advice, the other forum would be able to isolate the problem because of the specific knowledge.
For example, I know for my Mercruiser, there is no relationship between the key and the trim, but there is a relationship between the trim sending unit and the trim switches... but you don't have a trim sending unit on your Johnson. So the basic designs are different.
Good luck.
