Restoring a 1968 Whaler and will be getting the boat back from paint soon. I am going to install new thru hull tubes. Would this be a reasonable alternative to the brass tube that will need annealing and flanging (will need to buy the flanging tool). I read many stories of first timers having to redo after their first few tries.

In most areas you would be installing the tru-hulls you could not be able to tighten that backing nut onto the fitting. It just simply will not work.

Trust me, very veterans do not always get the tube done right the first time.....every time.

Here is a very detailed how-to:

Jeff's fine article on the method of replacement of through-hull fittings is also mentioned and hyperlinked in the FAQ article on hull drain replacement at

I plan to attempt this repair on my Sport 13. I'm going to look into the possibility of using [Marelon™], some other type plastic, or PVC material.

On a previous boat maintained in a slip for several years I used Marelon through hull fittings and shut off valves on the supply and discharge lines for the MSD. This was from the late 1970s until I passed the boat on to a new owner in 1999, a bit over 20 years.

Without further research I don't know if it is a good material for a hull drain tube on a Sport 13.
