    OMC Cobra Outdrive Seals (Replace?)

    Both of my outdrives (1988/89 Cobra 5.7) have a very little bit of water getting in. When I drain the gear oil, there is a milk-shake at the very end of the drain. <br /><br />I am capable of removing the drives, and do have a SELOC manual. I'm wondering on how difficult a job it is to (1)...

    1989 OMC 350/5.7 Cobra (two).<br /><br />I've had this boat for two years, and have changed the gear oil every fall since. Everytime, the used oil starts out slightly milky, but then flows brown, and does not smell burnt. The magnets have some metal, but mostly like metal dust as apposed to...

    Winterizing - Should I drain the antifreeze??

    Winterizing question (for Michigan). 1989 OMC Cobra 5.7L/350.<br /><br />I ran the engine to operating temp on muffs. Changed the oil, oil/fuel filters then ran 5 gallons of antifreeze (4, -60F and 1 -100F). As I noticed the antifreeze coming out solid, and at this point gone, I realized I...

    ESA for OMC Cobra Drive

    My OMC's shift very hard. After getting much needed help from this forum, I found that my port side ESA Switch does not "scatter" the ignition when clicked. My question is, where can I get a new EAS, or switch? And, does anyone know who much they cost ?<br /><br />Thanx
