    OMC 3.0 cobra exhaust manifold change

    I've had high temperature issues since I bought this boat 3 years ago, it didn't run hot but it ran in the 180's or so. I changed the impeller, water pickup tube seals, water circulating pump. Then finally it overheated briefly and I removed the thermostat. It ran OK, but not great. But it...

    removing lower gear case to service water intake tube.

    I think I have a leaky water intake, I bought the seals and I'm ready to separate the upper and lower. I also need to adjust my shift rod. Is there a gasket between upper and lower? Any tips on separating, I have removed the drive from the boat. Any tips on putting the two halves together again...

    OMC 3.0 Cobra hit the bottom

    So I wasn't paying too much attention and I hit the bottom in shallow water. Dug up mud and the boat felt like it popped out of gear. After I realized what happened I got out of trouble in deeper water, and everything looked like it was working and shifting fine. It really took the paint off the...

    cobra 3.0 winterizing after pulling the impeller

    I was extremely busy this fall and I was worried about a freeze up so I pulled the impeller, drained the block and manifold, pulled and drained all the hoses on my 1988 cobra 3.0. Well, now I want to start it up with the sta-bil ethanol treatment and fog the engine. Question. Do I need to hook...

    over-reving omc 3.0 bayline capri 1950

    I bought the boat this year, it is a 1988 bayliner capri cuddy, 3.0 omc. It came with 2 props, a 4 blade and a 3 blade. I tried both, although the 3 blade is really beat up, the engine will rev to 5K or more If I hit WOT. The 4 blade is a 13.25 X 14 and the 3 blade is a 13.25 X 15. The holeshot...

    Changed my shift cable, here is what I did. NOTE ** NEWBIE **

    I just bought the boat in March, I got it for cheap. It is a solid boat with very little or no rot, mechanically it ran great, didn't jump out of gear, and there were no nasty sounds coming from the engine or outdrive. BUT, it took a high effort to shift, and when I was on the water it didn't...

    can't get my lower shift cable housing to unscrew.

    I'm at the pivot housing, and I can't get the cable housing brass nut to start turning to remove. Any tips? Heat. I soaked it with pb blaster. I', using a crowfoot, maybe I should just cut the housing and put a socket on there? TIA 3.0 cobra

    automatic bilge pump indicator light

    I want to put an automatic bilge pump in my 19' capri cuddy. Either an attwood or rule, the type with the built in float switch. Is there a way of wiring in a light to indicate that the pump is running (drawing current)? I know I can do it with the separate switch pump type. TIA

    Do I have an extra hose?

    At some point in my boats life, the previous owner must have tried a heater install. I found the heater core along with the auto fan (both disconnected, leaking I suspect). It looked like a clever idea, just executed a bit unorthodox. In any case, when looking at photos of other OMC 3.0 engines...
