    1989 OMC Cobra 350 overheating problem

    1989 OMC Cobra 350 overheating problem

    The impeller part number I bought was the OEM number from the factory parts book, 0383307. It’s not a Sierra or off brand replacement. My boat is 100% fresh water. The port on the water pump housing does **** water when the water is turned on so the pump is being primed. And the water coming out...

    1989 OMC Cobra 350 overheating problem

    I didn’t feel like I got all of the impeller with just the back flush which is why I disassembled everything. Good thing to because I found more chunks that the hose didn’t dislodge. I did replace the thermostat when I had the housing off to check for debris. The stat is rated for 180, not 160...

    Omc Cobra fill indicator gasket

    Has anyone come up with a better gasket or oring for the level indicator on the top of a OMC Cobra outdrive? I've replaced mine twice and twice it’s leaked. There has to be something better than the overpriced plastic washer from Johnson/BRP.

    Swim platform support calculations

    I have a 36’ Tiara that has a 20” deep swim platform on the transom. I would like to increase this to approx. 48”. Currently, the platform is rock solid, is, no flexing when you stand on the edge. My concern is the extra “lever” a 48” deep platform will put on the transom and the support...

    Hard shifting OUT of gear

    I have a 1988 King Cobra 350 engine/outdrive. I recently replaced my non functioning ESA module and it now works. At the same time I also removed the drive and replaced the gimbal bearing.
