I have an early 1970's Sunfish with the old style DePersia Bailer Ad from 1957
The plug is missing
I have searched and it appears the old style old style DePersia Bailer is no longer made, the only source for replacement parts are salvage if you can find them. Several options exist for entire replacement bailers made of plastic. It appears (not conclusive) parts from the new style plastic one WILL NOT work in the old metal ones.
I sailed sunfish all summer, without using the self bailer feature once. I am looking for plug that I can use in the place of the bailer plug. I measured the plug hole, it seems to be about 1 inch or 7/8 of inch. I tried using a 1 inch snap lock drain plug, it is slightly to big. The only other size of this I found was 1/2 inch. I am not sure nor do I have the tools to measure the exact size of the opening nor thread count.
Have also tried the 7/8 inch rubber bailer plug and it will not fit in the threaded opening.
Looking for a solutions to plug the existing drain hole without replacing the entire bailer unit. Preference is an easily removable plug but would consider one that requires tools to screw in and out.
Size info I found this post about the DePersia Bailer Trouble is most of today’s plumbing fittings have tapered thread (NPT - \ / ) and the bailer is a straight thread 1-5/16 long, 7/8x14tpi ( | | ) – not a match.
