I changed a I/O hull to a outboard. I have my 3/8” plywood pieces for the motorwell cut and capped with 1-1/8” wooden dowel. I’m looking at matting and fibreglassing the pieces and wondering if there isn’t a easier way than cutting and applying Mat and fiberglass to encapsulate the pieces. Many little notches corners and the wood dowel on 3 of the 4 pieces to deal with.
I’m planning on using Raptor truck box liner or a similar epoxy coating to finish the floor, sides and transom of boat, and the motorwell. So just wondering if there is a epoxy I can use maybe without Matt to seal these pieces, and add some strength before I put on the final epoxy floor coating.
Spray epoxy
Re: Spray epoxy
I think the short answer to your question is, no, there is no magical shortcut that provides the same strength as an epoxy/fiberglass composite structure in a "spray on" treatment. To add to that, epoxy alone is not really considered structural. Without getting into the technical side of the transom modifications or design of the motorwell, i would say that you should probably plan on filleting and taping all seams and epoxy coating all wood parts at a bare minimum.
Edit... any more pics or info on the rest of the boat?

Re: Spray epoxy
Chopper gun and epoxy. They probably have an epoxy version of chopper. But hand laminating is best for what you are doing. Then fairing it all smooth.
That's it.
That's it.

Re: Spray epoxy
I would go for nice big fillets built with wood flour, Marine epoxy, and 12oz biax for glass. Forget any glass with matt.

Re: Spray epoxy
Second Fuzz. I didn't see you were wanting to skip glass. You gotta glass it all. 12 oz is really easy to work with.
Re: Spray epoxy
Thanks guys I pretty much knew I'm going to be cutting and hacking to get it done. But had a faint hope there might be a magic bullet. Some pics of my project !985 Sangster 19' was a I/O I've converted to a Outboard with a 125HP mercury.
Re: Spray epoxy
Cool project!
My approach:
If those pieces are not yet installed, it may be easier to glass both sides of each piece with some cloth. 6 oz will work, it would only be for abrasion, encapsulation and to prevent checking. Assemble the glassed pieces(maybe stitch them with zip ties) and fillet them, add some 12oz biaz tape to the seams.

Still loose pieces while I pondered a easy way. Like you say pretty much going to glass with 6oz all sides, fillet then reinforce joints..
Re: Spray epoxy
Also wondered if anyone out there had a a roll on idea for epoxy flooring? I want non slip, something I can get a color into that I can roll on the floor, sidewalls up to the gunnel and transom and new splashwell. I'm looking at this but pricy.
