Foam under seats

Postby Relentless » Sat Mar 02, 2019 11:52 am

This is what was under the seats. This is only one side. The styrofoam was so saturated it was heavy. But it wasn’t dripping water. As a matter of fact it didn’t even feel wet on the outside. I estimated it all weighed about 40 pounds.

Interesting that you write it didn't feel wet. I took some out the front of my boat, but that was dripping wet at the bottom, since water hat gotten into the tank from the boat sitting nose down when the trailer tongue had fallen off its support in a rainstorm, with all the water puddling against the drain hole in the bulkhead. . .

You have pix of your access ports?

A common problem. I replaced my waterlogged foam with swim noodles. Others have used liter soda bottles.
Note there is foam blocks packed into the bow flotation chamber as well as the seats

Hole cut in seats to get the foam out. Also best tool for cutting fiberglass. A multi tool with masonry blade.

Thanks for the picture. Didn't know about the masonry blade.

Many people swear by a Dremel tool for this job. I simply drilled closely-spaced holes in a perforation-like pattern.

Matter of not wanting to purchase another tool. It wasn't nearly as tedious a method as I had feared.

What size of access ports were you able to fit? This is a project I need to get done on my DS1 too.

Larger one for the front than the seats. Haven't gotten around to doing the seats yet. . .

I checked and the ones I bought for the project were 4" opening, but measure 6.5" in outer diameter.

You may check whether the seat fronts fit an 8.5" circle in which case you could get the 6" opening; for this project, the largest size that fits is indicated.

As I mentioned, I didn't go through with this at the time and the reason may well have been that I realized I bought a size too small.

Also, if you wait with installing the deck plate until after you've done the foam removal/replacement, you'll give yourself an extra .25" - .5" of opening to work with as the threads take up some room; that can make quite a difference I found.
