1977 omc stringer electric shift TRIM/TILT PROBLEM

markboutros · Aug 27, 2012

hey folks,

My trim/tilt has been giving me problems, I changed the motor last year so i know its not the motor....It will always go down but some time when I try triming up it wont work, all i hear is the siloniod clicking.

After i run the boat and bang it around the lake for a while it will start working again.

I think its the siloniod. It looks old as ****

What are your thoughts??

mine was doing the same thing. next time the sileniod clicks go back there and just jumper accross the sileniod with a short stout wire. that should tell you if the sileniod is bad or not.

but either way, probably a good idea to replace them if they are old as ****

which terminals do I touch together??

Re: 1977 omc stringer electric shift TRIM/TILT PROBLEM

One of the terminals will always be hot with the key on.

with a multimeter find out which one gets hot when you tilt up, then jump to that one.

dont quote me on this as it has been a while. but on MY boat the tilt up sileniod is on the starboard side, and the side that i was jumping to was the inward terminal, or towards the port side. Good luck

so basically i will touch the jumper to the power (which will be the red cable) to one of the 2 terninals (one terminal should be trim up and 1 terninal should be trim down) the 4 terminal is ground (with a black cable coming out of it)

Do i have that correct.

Agree with RED ... those solenoids are also cheap as ________ .

Do a quick check that your trunions are greased and that your clutch pack isn't all gunked up.

No, you have a total of 3 siloniods towards the rear of your engine.

1 for cranking / starting
1 for tilt up
and 1 for tilt down

the tilt ones are located directly behind the engine under 2 large looms of wires, the cranking one *should* be more off to the starboard side, mines is anyways,Its the one that is connected to the starter.

I have a ford, so that is what I am reffering to. I dont know what you have, a Chevy may be quite different.

Re: 1977 omc stringer electric shift TRIM/TILT PROBLEM

That makes scence cuz the solinoid right next to it for trim down looks brand new.

I will just replace that solinoid and call it a day

Thanks for all your help.

good call.

be sure to follow southkogs advice as well and make sure that everything is moving freely and lubed up.

btw, that isn't power trim
it is only tilt for trailering
