transom drains

[ScottinAZ]

This isnt so much a resto thread as a repair question. I was installing my drain plug and noticed that the drain tube is able to be spun inside the transom. Obviously this means that it isnt sealed to the transom effectively, but my question is, what is the best way to repair this, use a plastic multipiece drain tube, or install a new brass one? I dont have the tools to do a swaged end on the new brass one, so that is a consideration. I will be sealing the outside of the tube with 5200 regardless of the type used, Im just curious what those that have changed transoms and replaced these tubes have done before me.

Re: transom drains

My concern now would be for water in the surrounding wood, its gonna be wet so it has to be dealt with. You could try blocking the inside hole and applying a vacuum pump to the outside hole, see how much water it draws out, then flush with acetone to displace any more water. I would consider drilling a coring hole within a couple of inches of the drain to test for moisture migration, if alls well just seal it with epoxy.

You can make a flaring tool with a long bolt , fender washers and a cone to force the end of the tube into a flare. Hobby shops sell alum propellor cones, just drill the screw hole out to take a bigger bolt.

Alternatively, a ball peen hammer, brace the tube on the inside to hold it, place the hammer's ball in position and belt the hammer face with a second hammer.

My new splashwell tube was 1/4 inch too short, but I just installed a composite transom so water intrusion isn't going to be a soak problem, so I just glued it in place with plenty of 5200.

I don't regard plastic fittings suitable for thru-hulls below the water line.
Unless they are carbon fiber reinforced ,...which the white plastic isn't.
