Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

2. Old threads should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís thread (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new thread of your own.

4. If you have a question for the original poster (OP) and the thread is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old thread.

5. By starting your own thread, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

    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,


      Rick

            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.
