It is alleready sealed pretty well.The plug in the back of the boat, i had to replace mine about a month ago, i go to back out the screw and the screw head popped off of the screw shaft, really crappy quality. That may be a source of your leak, back out the screws, reseal with marine sealant ( i use 5200 but be very careful as it gets over everything, i suggest you mask the area.) and really get a good coating on the screws and the fitting when you put it back in. that may be the source of your leak.
I just did that last week it didn't make a difference. what i was wondering was does the fitting in the back of the cockpit where the rubber plug goes in go thru the hull and if it is a common place for a boat to leak from.yes, take the auto baler out and check the seal inside the cock pit and the auto baler screw in the hull, then refit the auto baler with new sealant and see if that fixes it
yuphmmm. this is a tough one did you check the grab rails?
Not sure what a O ring seal on the drain plug is. And there is no cracks on the deck. There are some minor spider cracks on the hull around the daggerboard trunk but when I bubble tested them there was no bubbles.and you have a O ring seal on your drain plug? oh and no gel coat cracks any where on the deck?
not 100% sure. I will check when I go down to the yacht club tomorrow.there should be a "O" shaped piece of rubber in between the drain plug and the drain plug fitting so when you screw it in it makes a seal
Today I went down to the yacht club to see if I had the rubber seal and I dont so I took out the brass fitting so that I could silicone it back on.
Would any leaks there be visible or would it be something a bit harder to see. I did take a good look around and i didn't notice anything but i could have missed it.And you can get a leak into the hull at the cockpit drain if the adhesive stuff that holds the cockpit to the hull (inside the hull) comes loose. The hull then can move relative to the cockpit, making any sealant placed there ineffective. If you have taken the brass fitting apart you should be able to check for leaks in that area. There are threads devoted to how to fix this. You generally need to install access ports in the back of the cockpit. I'd hope for a leak that's easier to repair, like the missing 0-ring shown above!
I was blowing into the hull and my coach was watching to see if it was bubblingHow were you pressurizing the hull to perform the soap/bubble test ?
Hey guys,
I have been noticing for quite a while now that my boat is taking on a lot of water everytime I go sailing. I tried a bubble test today: I tested all the fittings and screws as well as my gunwales. Nothing worked, I still don't know where it is leaking from. Any suggestions?
thanks in advance

We tested it first on the breathing hole and it bubbled. I have heard horror stories about boats blowing apart when you use a compressor.Blowing by mouth? I don't think you could create enough pressure to see bubbles
you should try low pressure pump,
I use a compressor on low pressure setting with car wash soap, you can find leaks very quickly this way
