Tilt problem, 1995 120hp Force

[glamerton]

When I took my boat out of storage, the tilt would not go up. Eventually with so manual assistance it started going up. The motor makes noise like it is turning, but it motor barely moves. It goes down fine. I manually lifted motor to the top locked position and removed the oil plug from bottom of motor. Lots of oil came out? Is this normal. How do you fill and bleed system and do you think this is my only problem?

Hello All,

I see I have had quite a few read my post, but no replies, yet. I have talked with a few local repair shops and they say we never have problem with the hydrolics, it is always the electrical. My problem is definately hydrolic and I beleive I have ruled out the piston as the problem area, with everything taken apart except for the piston, I can blow air in two of the three ports and the piston will go with one and down with the other. I have found a missing o-ring. But I am not positive if I lost it, but I must of. The third port has a bunch 2 springs, 3 or 4 o-rings, I believe these are what hold the pressure in the piston, so that it won't settle down, this may be my problem area. I had a friend tell me to coat the o-rings with silicone paste and reassemble. I will be doing this with the replacement o-ring I bought.

Any comments are appreciated,

Thank you,
Gary

I'm not positive but I think it should be filled in the down position.
The electric motors CAN go bad.Sounds like you have it apart.Take the motor off and check for corrosion and rust,Then make sure the battery connections are tight.
If you plan on keeping the motor get the factory manual.That will help a lot.Jerry

Hello All,

I have my solution figured out. As Fab9stated, that it is always electrical, is the response I had received several times. I was able to determine that it was hydrolic, and it was not related to the motor or cylinder. I narrowed it down to the pump /diverstion valve under the motor. I found that the hydrolic port that goes to the cylinder was plugged. It was a very small hole and I was able to get a fine piece of mechanics wire partially through the blockage. While inspecting the unit from the other side, which I realized was directly lined-up the manual bleeder valve. I found a small piece of plastic the size of a BB lodged in the hole, which broke off the tip of the bleeder valve, which is why it wouldn't go up or down when the bleeder valve was removed. I had the option of replacing the bleeder valve for $43 or the whole pump / diversion valve for $200 (Ebay NOS). I elected to replace the unit and problem is resolved. The part no. is 8116707 and the description is Pump manifold kit. It is no longer available from Mercury (Force).

Thank you,

Gary
