1975 SF 18 going under the knife.

[chuckcallahan]

Purchased this ‘75 a few months back and have been stripping her down and doing some probing.

The plan is: Replace the transom, those core samples can really smell! This will be replaced with Coosa. Not looking for a full transom, just raise it some, to ease the following-sea pucker factor, suggestions please. Then I would like to raise the deck, and re-core with Nida, somewhere around 2” graduating down to 1” closer to the stern. New 50-gallon tank moving it forward some. Rewire, re-hose, then new deck hardware and finally paint with Alexseal.

The engine per my mechanic, a 2000 Johnson 115, is good for at least a couple of seasons so that will remain as is for now. Picture is of the day purchased. Boat is in decent shape, except for the transom and what maybe lurks below deck? Hopefully no major surprises. But most know how that goes. I will try to post often with pics and look forward to critiques and suggestions from the abundance of knowledge that resides in this community.

My first question. Is there any advantage or disadvantage of going with a single, 1 ½" Coosa board vs, (2) ¾" boards for the transom?
