Re: Huck Finn 20. Question on transom thickness?

Postby jeffmo63 » Fri Sep 05, 2014 11:14 am

It is quickly getting to be that time to build the transoms on my Huck Finn 20. As most of you know I am building a tri-toon configuration with an outboard motor mounted to the center pontoon. The plans do not detail this installation. What transom thickness is recommended for a 25-40 horsepower motor? I was thinking between 1 and 1 1/2 inches would do. Also, what type of reinforcing do I need between the transom and the sides? Any thoughts or ideas would be appreciated.

I found the answer to my question on page 66 of my "Boatbuilder's Notebook." Thanks Glen!

You make me laugh so hard Mike! I'm trying to get a last push in before the cold weather sets in. The epoxy doesn't do well once the temperature drops.

Pic is of the three completed stem assemblies. They have one coat of Poxy Shield on them. They will get an additional coat. Next; mounting one of them to the building form.

Today I cut out the trasoms. There is a lot going on back there but careful study of the plans should provide some clarity.

Here is what the transom frames look like. They overhang the plywood transom slightly so that a 6 degree angle can be cut,

The transom frames are glued to the plywood. I used countersunk #8 x 3/4 bronze screws instead of nails.

My first completed transom. It took a lot of time and study but I finally got it done. Next step; attaching the stem, bulkheads, and transom to the building form.
