I completely removed the original deck drain from my ‘79 Sunfish because it was corroded beyond repair on the inside of the hull. I have since made some minor repairs to the opening and filled the original pin holes (one was compromised during the removal) with Flexpoxy. I have sanded and prepped the opening, and dry fitted the new plug. The new plug from www.sunfisfpartsdirect.com came with two pins, but it has 3 holes on the flange instead of two as shown in the picture from their website (below). I’m assuming the third hole is just an extra/optional hole in case placement is an issue, but I’m curious to hear what y’all think? Also, do y’all have any advice on what size drill bit to use? Thanks.
Presently, I'm feeling your pain.I managed to get my deck drain open with repeated application of WD-40. I hear water sloshing when I move the boat but I can't seem to manage to tip the boat in a way that causes anything to come out of the hole. Is the water trapped somehow? Is this common? Any suggestions on what to do?
If possible, Rest it against a wall with the drain facing towards the wall at the bottom. Have the boat at an angle and not flat up against the wall.I was able to flip the Sunfish on its side while it was on the trailer. I got quite a bit of water to come out of the deck drain. I’m not sure I got it all, but it’s an improvement.
Where did you get your replacement deck drain assembly and did it have 2 pins and holes or 3? ThanksSounds like the transom plug may be clogged, possibly foam bits? I have been told on this forum that transom plugs don’t work particularly well in Sunfish due to the foam filling the rear of the hull. I installed a new/replacement plug in the factory location this weekend.

If it's going to be stored for weeks (or the entire winter season), I'd thread a one-foot length of clothesline* backwards into the drain. (preferably cotton, but any rope will work). It'll slowly syphon any remaining water out.If possible, Rest it against a wall with the drain facing towards the wall at the bottom. Have the boat at an angle and not flat up against the wall.
