1975 Sunfish Drain Plug

Thread starter #1
I bought a "new style" drain plug from Sunfish Direct for my 1975 boat. The year is clear from the serial number stamped on the transom. It is too big, does not fit. Everything I've read says there are two drain plugs - "old" and "new styles, with the changeover year 1972. Can anyone explain why the "new" plug does not fit a 1975 boat?

I ordered the same thing once upon a time got the same results. Not
worth the trouble. You can get a plug from the plumbing section of
True Value hardware stores or order a Garboard drain plug online.
Wine corks work or you can just sail without the plug for now.

The older pre 1972 deck drain plugs were press fit into the deck with no flange. The screw in plug part bottomed out at the internal flange. Then in 1972 they added a flange and used the split pins to hold it onto the deck, similar pin that held the mast and halyard bases on the mast. The plug you purchased is the third style deck plug made of plastic. The only issue with this style is that it is not flush with the deck. Also as you found out needs a larger hole in the deck to be installed. You can make a bigger hole or buy a used deck drain plug. I have a couple of these. I prefer the new plastic ones as they are replaceable for cheap money.

Thanks, been using corks for several years, would like to screw in a plug and not worry about it popping out or needing corkscrew to remove it.

Thanks, I meant the bailer in the cockpit, not the drain plug on the deck.

The difference is not too significant in the plastic bailers, but there are two distinct differences in metal bailers. ("De Persia").

Until I get my metal bailers sorted out, I'm using a NAPA "adjustable rubber freeze-plug". It should be in stock @ $5, and measure 1¼". Put the larger washer inside.
