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!

Hey Tobycat,<br />Sounds like you're low on fluid in your tilt/trim. <br />Backlash

Tobycat,<br />It might the "hammer blow coupling". This is what allows the lower unit to "break away" upon impact it keep it from ripping away from the boat!<br /><br />I do not know about the 74 omc outdrive, but my 78 has a electric motor that drives the tilt. Its attached via the coupling to a worm gear, thru the intermedate unit to a clutch pack assembly which is attached to the tilt gear. It might be the clutch assembly or the worm gear as well?<br /><br />just thinking outloud...
