    OMC Cobra w/ 5.7 Holley 4010 using way too much gas

    Ok , thanks to my old automotive Holley I figured out how to get inside this thing without tearing everything up. The floats are how I found them with one not even coming close to being level to the housing-right side pic. Found some gummy debris at the rear jets as well, odd for a rebuilt I...

    wear on the upper gear case flange OMC Cobra

    I have now got the engine aligned and began cleaning up the mating surface on the gimble . When I got the old gasket and gobs of permatex off I found an area near the shift cable that is ate up . Don't know if a leak caused it or corrosion or what but it is enough to make me concerned . I am...

    for the last two days I have researched what the plug gap should be for and NGK G-power---UR4GP plug for my new rebuilt 5.7 Carbureted engine. So far I have read answers from .30 to .40 .

    More stupid questions--below you will find pictures of a coil and something that I am not familiar with so I am asking anyone what this is and what it does . It almost looks like some kind of a second coil but does not connect to the distributor .
