After noticing a piece of the original brass drain tube was starting to break off in the engine well area of my '93 Seafarer, I realized I should replace mine, particularly given the 4 stoke is reported to push the two lower scuppers below the water line and it will be left in the water for the season.
In case anyone is interested, I am using 1 1/4" OD diameter brass tubing from McMaster-Carr, part # 8950K832 ($42 for 3' section) and a flange tool by Moeller part # 02070400 (both BoatFix and LowCostBoatingStore.com had this part for a good price: $30 excluding shipping).
Plans are to remove the old tubes, widen the hole a bit to allow room for a few layers of epoxy paste to seal the wood end grain, then redrill for 1.25". Once that is done I will install the new tubes using 5200 and the flange tool. I am told I should heat the tube up and drop it into a bucket of water prior to installing to soften it so the flange will form without splitting.
I'll report back on how things go. If anyone has any further advice, please let me know.
