Trim Promlems on OMC Cobra

[LinkAmerica.net]

Hello all,<br />I have a 90 Chris Craft with an OMC Cobra 5.8L 351. After letting the boat sit in my garage for about 7 months, we are haveing problems with the electric trim. We took it out for the first time this weekend and I noticed that the motor sounded really slow, and the trim moved slow also. Now, when you try to adjust it with the switch on the gear shifter, it makes a clicking sound coming from the motor. I was wondering if this could be a bad switch or a bad relay. I can tap on the motor houseing and it starts to work breifly, then stops. I have not tried to do anything other than that because it was getting dark last night. I found this forum and this is the first post I have ever made. I am hoping to get some helpful hints and tricks before I go home today and start diagnosing it. I have a Clymer manual and was reading in it last night. Also, last year, when you would be driving the boat and adjust the trim, sometimes I would get shocked from the switch on the shifter. This is why I was thinking it was a bad switch. If not that, maybe the relay went bad? Could this be the cause of the clicking and the slow speed it raises and lowers? I didn't think that low fluid could cause the motor to click because to me, clicking is an electrical problem. Also, seems like the relay is getting SOME power because I put my finger on one of the leads by accident and was like !<br /><br />Any info would be great.

Re: Trim Promlems on OMC Cobra

i've been reading here and found a couple of things that make me ask more questions. Is my motor the kind with solenoid switches on the block? It is a 90 5.8L OMC Cobra. The trip clicks when I push the buttons up or down. I am going to trace down wires today when I get home and test some things with voltmeters. Would it be ok to hook the batery directly up to the motor to see if it runs? Hopefully it will be something easy.

First off you shouldn't be getting shocks from 12 volt accessaries like that. You could get em from the high tension wire coming off the distributer or coil. If your hearing clicking from the selenoids it could be low voltage or bad connections.the selenoid could also be faulty.

Thanks for the input.<br />Took everything apart tonight after I found that all the wires had good ground and power coming from the battery. I checked everything in all the right places. I got to the motor and it is dead. The clicking is not from solenoids, this model does not have any, it only has a relay breaker. It was clicking because there was no power going to the motor. The motor is gone, completely corroded and the magnets are cracked and the brushes are rusted. Going to have it rebuilt from the local motor place and should be doing good after that. Local marina said motor would be 250.00. Fawk that. I will just rebuild it. Anything I should watch for when they do it?
