1974 omc outdrive

[tobycat]

Hello folks,<br /> <br />When I was towing my 1974 carver to the river the outdrive was lifted. When I got there, it was down and slipping...I could pick it up and down. Usually it would stay locked. The lift/down button either way just spins the motor.<br />Is there anything that is common to these outdrives that would cause this? In reverse the od kept popping up..forward was ok. Is this a solnoid or a clutch pack problem? Any suggestions would be appreciated. <br /> <br />thanks

I have a 76 OMC, my lift motor was out when I got it. There is a pin inside of the shaft that I am told breaks. Of course you have to take out the whole inside of the tilt trim up/down gears and all that stuff to get to it. There is also supposed to be a clutch in there that is supposed to avoid damage to your drive if it hits something. You may want to check that out. What part of california are you in? I am in So.

Hi Tobycat,What you are discribing sounds like a loose chutch pack to me. On some of the newer units there was a plug on the stbd, side of the lift mechanism that could be removed and it could be tightened up with an allen wrench.<br />Might be worth checking.

The tilt clutch which raises and lowers the outdrive has many shims in there. All held together by a big snap ring. To increase tension add shims. It could be snap ring came off. Mine is a 1980 series 400 and I actually removed two shims because it was too hard to tilt up. Even after I took out two shims mine still does not kick up up on a hard reverse. I may some day take out two more. It function is to save the outdrive if you hit something like a rock, log or whale. Also might want to make sure it ha right oil in it. Mine uses 30 weight motor oil.
