89 150 Merc trim problems after trim-motor rebuild

[ahsah]

I've been searching the archives for a couple hours can't find the answer so here goes .. . .

I was having problems with the tilt/trim on the 150 merc. the solenoids clicked but didn't operate after setting for over a year. I took the trim motor off and took it to a rebuilder and had it rebuilt - he said it was real bad inside rusty etc. I put it back in, put the recommended 5-30 oil in it and wired it up. It worked for about 30 seconds Tilted down okay - I had to click the up several times to get it to work, tilted all the way up to remove the support to the trailer frame and then there is just clicks again. I opened the bleeder valve to lower the motor (let pressure off) lowered the motor checked the fluid level; still only clicks. Not the switch, because it is in a bass boat and I tried another of the three trim switchs.

I did re-mount the unit in the vertical position it was horizontal - couldn't check the fluid without removing it and holding the unit vertically.

Any suggestions? Could it be a ground? Where would I put a new/better ground?

Thanks
Steve

I too am have similar trouble so am looking forward to the replies and will watch this discussion. Mine, an '83 200hp Merc. I was working fine until I removed the motor/pump unit to check/add fluid. I unhooked no wires, no nothing, no I get only solenoid clicks and the pump wont run. It worked fine only seconds before, now only click.

have you checked/tightened the connections on the solenoids? starter solenoids can also have the same problem, not made well at all

With mine, the '83, I called my mechanic this morning and he told me to tap it with a hammer to see if that helps and then to try to short the terminals if that wont help. He said I can get a brush kit for it if needed. I will try all that this evening and let you all know what I find out.

Well first off if trim is in boat its not a 89 model motor, and you likey got bad solenoids. Try jumping across solenoid and if it works that solenoid is bad.
