    Default 88 omc outdrive

    trying to get outdrive off 88 bayliner cuddy cabin 5.7 with omc out drive, will not come out, got it to seperate but will not come out. tried prying as much as i dare, tried using trim cylinders to push it out, ot it out about inch and a half, but it pulls right back in. i am new to boats but have been a gm and heavy equipment tech for 20+ years, don't know what else to try short of a sledge hammer or 5 gallons and a match. any help would be appreciated

    The 88 OMC is a Cobra, very similar in many ways to the Mercruiser.

    If it just wont come out, it may be hydraulically locked into the torque coupler.

    Would be wikking to bet the alignment is out of whack and causing it to grab, you can always loosen the motor mount adjustment towers and raise/lower the engine to try to find the sweet spot.

    Another little stupid trick to try is to have someone turn over the engine with a wrench while attempting to pull it off. Remove the coil wire for safety reasons.

    These can be a bitch.

    Good luck

    Does not make any difference neutral or not.

    Try raising and lowering the engine.

    The torque coupler is a rubber hub and there is not a whole lot of slack in them, more importantly, impact will do nothing.

    You may be able to shoot some penetrating oil onto the splined shaft with a straw on a can of penetrant.
