Re: Mako 254 rebuild

Nice the foam came out like that. Are you going to put a deck in then put the cap on like a 3 piece or you trying to get it back to original 2-piece?

Re: Mako 254 rebuild

If you use epoxy and treat the penetrations right it will last forever.

Re: Mako 254 rebuild

So looking at the properties, the compressive strength of the gator board is 800 psi and coosa is 960-1100. That is the meadure of crushing strength. The coosa will take more to compress. The flexure strength of gator is 2900 psi and the coosa is 5200 psi. This is how strong it is in bending. Again ...

Re: Mako 254 rebuild

Plywood is going to be much stronger and require far less glass to develop the equivalent strength. That said it is twice as heavy but that might be 30 pounds in a transom. My general experience with polyumac is that it’s properties are not as good as the “main stream” products. Particularly the foa...

Re: Mako 254 rebuild

I have lots of experience with polyumac but not the gator board unfortunately. Not sure you caught it but we are in the middle of the same project on my neighbors 224.

Re: Mako 254 rebuild

Sweet! Love the 254. There is a thread on here where I started a 258. Was working on making it a CC when the Bertram happened. Built a cap for that one. That is one of the best hulls mako built by far.

Re: DAYTRIPs Bertram 28 Strech

There is a thread on here where we did a bracket on my nephews 221. Helping my neighbor right now with his 224. Did his transom in coosa 2-1” pieces and will build a bracket at some point soon

Re: DAYTRIPs Bertram 28 Strech

Hey seabird, I think I outlined the layup schedule somewhere above. It is 6 skins per side of the clamping bracket, stringers are the same. The tub is 8 skins. All 1708. The transom on this will be cored but not to carry bracket. I have some 2” foam I will use. All load goes thru stringers for the m...
