Thanks Jester.....I can see that whoever cut out the pre stamped hole was a hack and made it too big. It took all of last year and this year so far for it to fall out. I will try some tape, and/or an o ring maybe, pretty sure I'll get it fixed. Yunno, there has been quite a number of small nagging issues with this boat. I DO like my boat, but still.........maybe the difference between Moomba and Supra is the Moombas don't get QC or QA before they leave the factory, or maybe they use the Moombas to train new people!!!
