    OMC has a "gear whine' when turning, clunks under load

    First of all, thanks to all the fellas that are so willing to answer questions on this forum, and the forum itself, for offering so much past information. I have a 91 four winns 4.3 OMC Cobra. First of all the problem is, when I put it in gear, it performs flawlessly, until I get the slack out...

    Not getting water up to thermostat on muffs

    I've got a 91 four winns, 4.3 OMC Cobra. Just replaced engine, and had upper drive rebuilt. After running it the first time (on muffs), it got up to 190, so I shut it down, and started checking things out. It took about 5 minutes to reach that temperature. When I pulled the water hose...

    Automatic oiler on outdrive

    Seems that running an outdrive low on oil is a common problem. I bought my first boat a couple of months ago, and even though I knew from the research I had done before I bought it, that there were numerous things I should have checked before taking it out the first time, I went out anyway. I...

    Convert to SEI or rebuild?

    I expected to see a lot of threads discussing all the people converting to SEI, but don't see that much, or maybe I don't know how to search very well. I'm looking at either rebuilding the upper unit of my (91 4.3 Cobra OMC) outdrive, or converting to S.E.I. unless there is some other option...

    Filling engine with water first time

    I just replaced my engine (91 4.3 omc cobra), and wasn't thinking about filling it with water, til I got all done. Question is, I have an extra gasket for the therm housing, should I just remove it, to fill the engine, or is there some trick I don't know about? I know I can fill the water pump...

    OMC outdrive question

    I'm getting ready to re-install my outdrive after replacing the engine, and noticed that the splined shaft doesn't spin freely in neutral. Is this normal? To me it feels like a bad bearing, but I'm new to boats, and it only has 180 hours on it. The oil is clean, and there was no sign of water...

    Beaching platform

    My wife grew up on the lake, and they always beached there boat using a car tire. This weekend, I saw what basically amounted to someone taking the carpeted 2x4?s off their boat trailer, and mounting them to a platform, and beaching there boat on it (this is at on a fresh water lake). I had...
