    If this is a garboard plug (brass plug with threads) it is possible that the flanged part has worked loose from the hull. There are usually three screws holding this on, and it is not unusual for the fitting to come loose from the plug being too tight and forced in, and back out.

    Easy fix...remove the flange...clean all the areas...reseal with 3M 5200...replace the screws...and wait for the 3M to cure.

    Be sure NOT to put the plug in too tight...it is a pipe thread, and does not need to be overly tightened.

    Howdy,


    You're sort'a in the wrong section. This is the I/O & engine section.

    Your question might be better asked in the Boat restoration and Building section.

    A Mod(erator) will probably be moving this thread for you!!



    Now having said that, yes........ There can be a problem in this area sometimes.


    A lot of boat builders do not seal that area well and if you get cracks in the fiberglass, have old holes that had screws in them that are no longer there, bilge drains that are not well sealed, they can leak....transom mounts that are not sealed properly, etc etc etc.....

    You can have leaks. They're usually not all that hard to find but you have to have the boat in the water and good bright lights to see where they are!



    Regards,

    That's natural...some will even remove their inside mounted plugs while on plane, and the water will exit from the bilge.

    Did you figure out if your plug screws in?

    So you're saying that it doesn't leak just sitting.


    It leaks when the engine is running at idle?


    Well, that MIGHT be an I/O thing after all!!


    You have a hose that runs from the transom to your oil/PS cooler (if installed) and then to the thermostat housing.

    The hose is connected to a metal tube that goes thru the transom back to the raw water pump port on the drive.
    If that tube (#68 below) is corroded, cracked, or the hose is loose, you could get water out of the it back there that would appear to be coming from the transom

    I just replaced the garboard flange and plug on mine last weekend. When I unscrewed the plug last Fall, I saw the flange shift just a bit. That told me it was time for a re-do.

    Just as described, unscrew the old flange at 3 points and pry it out. It'll be hard to break loose, but a small metal putty knife tapped in around the circumference freed mine. Scrape the old sealant out of there. A good bead of 5200 and some new screws and you're set.

    rock10,

    I actually remove drain plugs on my flatbottom to let water out while on a plane, but remember to put them back before dropping off plane.

    I see you have determined it's not the drain plug afterall. Good luck and I hope it's not too costly to fix.
