Hi all!

I have a 1984 Johnson 75 hp seahorse motor. About a year and half ago, I had the trim tilt motor and hydraulics replaced.
Never had an issue after that.
Ran the motor in the driveway this weekend and try to trim up the motor, "click". Try to trim down the motor, "click".
Motor wont go up or down. All I hear is one click, in either direction.
Are the relays making the clicking sound and could both of them blown out at the same time?
Any easy way to check the electric trim motor (I sure hope it is not the hydraulics again...)

Thanks all!!

Before anything else, try tapping the trim motor area with a rubber or nylon hammer, or the handle hand of a large screw driver, etc. Sometimes the trim motor will develop a "sticky"spot that a little vibration will break loose. If that works run the engine up and down a few times and your problem might be solved.

85 percent of the time if its electrical..its a connection..check the wiring connections and greasem with special electrical grease to stop corrosion

we have the same problem on our 1993 Evinrude 90. we found it was the brushes in the trim motor getting stuck. try tapping the hydraulic motor with a hammer and lubing the brushes with thin oil like 3 in 1 oil.

First step is get a test light and check the connections at the relays. My trim switch in the throttle handle was bad and stayed on and fried all of the relays.

The manual will guide you through the connections - my 150 has multiple relays on the rear of the motor in a small plastic "box" for lack of a better term. The trim motor works by reversing direction and it is possible to use a jumper to bypass the relays and direct feed the trim motor from there to see if the motor or a relay is the issue.

If you have low voltage in the main supply or a bad ground to the relays that could cause a click as well.

Hope this helps... all of the parts including the harness were available for my 1987 Evinrude 150.

Thanks all! Electric and relays good. Brooks - A few good whacks to the electric motor and it starts to run! In the process, I noticed my manual trim tilt screw is stripped. Now I need to figure that out. Any ideas on how to get it out?

One way would be to center drill the screw and use an easy out, You can try to clean a the screw and use a some JB weld or some other material that bonds really stronge, and attach it to a bolt and let it dry, (This is difficult and I do not know if it will work or not depending on if the screw is to tight) or take it to a welder to do the same. When you replace the screw get one that you use a scoket to remove and do not over tighten...Good luck

Thanks Contender! I gave the easy out a try yesterday. I can't find my centerpunch so my drill was wandering around too much for me to continue. I will try it again, I may want to hand this over to a "pro". I'd hate to mess up the threads for this valve. BTW - the manual release valve is $70 of this motor!
