Johnson GT 150 Tilt/Trim

[87Chap]

Im having problems with my motors tilt and trim. for some reason when we press the switch it does not go up or down. THe wiring is sound and very new. (but possibly wired wrong??) We removed the engine cover and located the relays. when we removed one of the relays the motor would automatically go up. when we replaced that one and removed the other the motor would go down. so we know the TNT motor works. posibly a bad relay?? any help would be great

Thanks

The trim motor starts running when you remove the relay?

Re: Johnson GT 150 Tilt/Trim

What you are describing should not happen. My guess is that it is wired incorrectly. OMC made a change in motors and wiring a few years earlier. They went from a 3-wire system to a 2-wire system. You may have some incorrect parts/harnesses mixed on your engine.

Me and my father in law had the same exact problem with our 1992 150hp GT tilt and trim. After looking around, we found that one of the relay's under the motor casing, in the back of the motor, was shot (hella was the brand), we replaced that and have not had any problems with it so far.
