    Where's the grease?

    I just got done replacing my u-joints on an '88 OMC Cobra 5.7. After getting everything put back together I went to grease the u-joints with Merc U-joint / gimbal grease. I can tell the u-joints filled up with grease as it got progressively harder to pump, but I can't get grease to oooze out of...

    1988 Cobra U-Joint Bellows

    I have gotten the drive off the boat and took a look at the U-joint bellow. I thought someone said this could be done without removing the pivot housing, but it looks like it will be a real bugger.... Does that pivot housing come off just by unscrewing the hex bolt that runs through it? If so...

    OMC 350 and 1.65 gear ratio

    1988 OMC Cobra w/ 350 GM SBC<br /><br />I made one of those drive stands with casters on the bottom, man what a back saver! Thanks to everyone on the pics and direction there. However I pulled the drive today and checked the gear ratio. The drive itself has a tag on it that says 5.0 (but I...

    P/S Oil Cooler

    1988 5.7 Cobra sterndrive.<br /><br />I took my P/S Oil cooler out today to pressure test. When pressurizing the water passage, it is leaking at each of the "end caps" (between the water passage and the outside air). I believe it holds pressure (20 psi) in the oil passage (results in the...

    OMC Gasket Sealing Compound

    In my manual for my '88 5.7 OMC Cobra, it keeps refering to OMC Gasket Sealing Compound. What should I use as a substitute, that could be picked up preferably at my local auto parts store? Thanks!

    What is this piece?

    1988 OMC Cobra 5.7. On the starboard side of the intake manifold is (towards the center, under the carb) is a small piece of coiled metal with a cover that is held on by two screws. What is this? I believe I may have damaged mine (which already appeared to be old rusty and not doing anything)...

    ?? Prop questions ??

    I have an ’88 OMC Cobra drive (on a 21’ VIP cuddy, ~ 3000 lbs). Will any 15 spline prop fit this drive, or are they manufacturer specific. I guess what I am asking is will a 15 spline 14 ½ x 23 mercury (mercrusier) prop fit my OMC cobra and vise versa?<br /><br />Last year I dropped a new...

    OMC Cobra Gimbal Bearing / U-joints

    I plan to remove my '88 Cobra drive this spring before boating season begins. How do I inspect the gimbal bearing to make sure it is ok? Or is it cheap/easy enough to just replace no matter what? <br /><br /><br />Also, I have heard by looking at the U-joints you can not always determine if...

    5.0 / 5.7 Impeller Question

    I have an '88 Cobra drive. I can read off of the tag that originally this was a 5.0 drive, but when I bought the boat it had been fitted with a 5.7 SBC. I assume the gears were changed to 1.50 (plan to check this comming spring). I am going to replace the water impeller in the drive, but...

    OMC 5.7 Power Steering

    My 21' VIP with '88 OMC 5.7 steers very hard. I am sure there is a leak in the system somewhere, as I can refill the power steering pump and it seems to get better but gradually worse (as the fluid leaks out I am sure). <br /><br />Just wandering if these power steering pumps are marine...
