    Sagging fuel tank causing water to get in the fuel?

    Any help would be appreciated! The Sunbird is in the shop again after having the sending unit replaced last year. The shop is saying there's water in the gas again due to the new sending unit becoming corroded like the last one, due to a sagging gas tank. They are saying they can't patch it...

    Is there no classified section here?

    I never thought about it until now, but as I search for a OMC outdrive I don't see a classified section here on the iboats forum. Am I missing it? thanks.

    loss of 800 RPM due to bad ground?

    Hello, I have a 1991 Sunbird 262 Corsair with 4.3 GM V6 OMC outdrive, and std. aluminum prop. The boat starts and runs great, however, there are times when the engine loses approximately 800 rpm at WOT. Normal WOT rpm is around 4400 (I believe, it's been a while since out on the water) and at...

    how to remove water stains from cabin upholstery?

    I am surprised my search didn't offer up more results. I'm wondering how to remove water stains from the cuddy cabin's upholstery. It is a fabric material, and the stains will not brush or clean out. We've even tried a marine fabric cleaner, no dice. Is this something Magic eraser will do...

    how to run transducer wire through hull

    Hi, the previous owner of my boat added a Humminbird Piranha fish finder, but ran the transducer wire through the combustion vent in order to get through the hull of the boat. I don't like the way the wire looks running through the vent, but how do I run it through a hole I drill in the hull...

    Boat ran into me, should I make him pay for damaged rubrail?

    OK, so a typical day at the ramp. It was packed and the guy next to me gets his boat all squirrely on the trailer and runs the back of his boat into the side of mine. All that was damaged was the rubber rub rail that goes around my boat, and the metal trim piece the rub rail fits into. Took a...

    intermittent WOT problem on 4.3 OMC

    Hi, I have one of those weird, intermittent problems that is hard to trouble shoot. My 4.3 OMC usually runs great and hits about 4600 RPM at WOT with a little trim adjustment. This is the recommended RPM's for this motor. However, all of a sudden, the RPM's will sometimes drop about 1000...

    Is it OK to run the bilge pump dry?

    I've done a search and didn't see an answer, but I am curious.... My first boat, a 1991 Sunbird Corsair 198, takes on a small amount of water. The bilge pump doesn't have a float switch yet, so sometimes I hit the bilge switch to see if any water pumps out. If there isn't enough water to pump...

    lower end oil looks like a science experiment!

    Ok I am a newb here and on my first boat, but this is puzzling.... I checked the lower end oil in my 4.3 OMC Cobra outdrive, and when I removed the check screw....green, frothy liquid oozed out the top and ran over the sides. I mean this stuff reminded me of Peter Brady's model volcano...
