I recently discovered that the transom on my '62 Larson All-American runabout is rotted to the point of replacement. The through hull fitting for the drain plug is right in the way. What do I do? I will have to destroy it to remove it so where can I get one or have one installed? Would I be better off separating the two halves of the boat, pulling all of the wood out and using Seacast, or cutting through and removing the rear fiberglass on the transom? I dont want to compromise the integrity of the boat so I am strongly against the last method.

If you can separate the two halves, that will be your best bet.<br /><br />Wal-Mart has replacement drain tubes if I am remembering right. I think I saw some within the past week.<br /><br />I have heard of and read about Sea Cast but have never used it. From what I have read it should be a breeze compared to glassing in a new block. I would not cut the outer skin except as a last resort. When you get everything cleaned out just put the drain tube in place and seal over each end of it with tape (duct tape maybe) to keep the Sea Cast from leaking out. Then you can clean up the hole after everything is poured and set.<br /><br />I did a Crosby sled once that turned out great. I cut away the glass at the very top of the transom and dug out all the wood. I had to take out the drain tube too. I dry fitted a new transom block and pre-drilled it for the drain tube. Actually I drilled the hole oversize, filled it in with resin then drilled it to accept the drain tube. I poured resin into the transom cavity and pushed the block into place, inserted the drain tube and applied mild clamping pressure to the transom till the resin set up. I had a few small voids (due to resin seeping through the inside skin) which I poured full of resin just as soon as the original pour had set enough to retain it. Last of all I replaced the glass I had cut from the top of the transom.<br /><br />It was a lot of work but the boat is still in use and is probably as strong or stronger than when new. <br /><br />Good luck.
