Re: 1972 Formula 233 Project

I will have to paint my bilge because gel coat won't stick, right?

correct

Second question: Should I use poly resin and csm on the bottom of my deck

Depends on how you plan to join the bottom of the deck to the top of the epoxy coated stringers. If you plan to use epoxy PB to attach the deck, then you can use either epoxy or poly & CSM on the bottom.

and then poly and 1708 on the top if I want to gel coat it?

Correct, but 1708 will likely telegraph thru the poly resin, so a finish layer of CSM would be smoother after gelcoat

Lookin Good! Good work, & Nice boat, That reminds me of my old 79'- 24' SeaRay cuddy, very similar.

Re: 1972 Formula 233 Project

Uhmm there's really no reason to use 1708 with Epoxy. It actually wastes resin and gives no benefit to the lamination. You can use regular 17oz biaxial fabric and get the same strength with epoxy. The mat stitched to the fabric in the 1708 is for the Poly to bind the resin to keep it from breaking apart.
If you're going to gelcoat the deck there's really no need to put 1708 on the top. 1708 is used for structural strength and it's not needed on the deck surface. I'd use a layer of CSM and then a final layer of 6oz cloth unless you want a bit of texture on your deck and the 1708 like JBC says will give you that with the pattern bleed thru.

I REALLY like your fabrication work..Top Notch!!!!

Thanks, Im trying to go slow as to make as little mistakes as possible. I hate do overs. LOL.

I think I will either use PB or just bite the cost and do 5200. Not real sure yet. I was going to use the 1708 just because I had so much of it. I still have about 75 yards. If the CSM will give me a better finish I will go with that. I was going to make a snap in carpet kit for the lake trips but I would still like to have a nice finish for when we take it out to go diving and fishing.

Yeah the do look like close cousins don't they? Really nice boats. I boat this one for many reasons. Love the idea that I can run to the lake with it for a weekend or take it to the sea of cortez to snag some yellow tail.

I think I may do a small test piece before I get to that point. Like I said Im going to do a snap in carpet kit for the lake but don't want it to look to hideous when I have the carpet out on the fishing/diving trips.

Transom is tabbed in with two layers of 1708.

Re: 1972 Formula 233 Project

This might be a little overkill but I decided to attach a piece of 1 1/2" pvc to my transom drain. I glued it up with 5200 and then filled the small void with an epoxy fines mix.

Re: 1972 Formula 233 Project

Ill obviously cut it down and shape it in after it sets for a day.

Re: 1972 Formula 233 Project

Started attaching my floor ledgers to the side of the hull. Stuck on now with some epoxy mix and will come back and tab them in.

Re: 1972 Formula 233 Project

So Im finding myself pondering again over what type of power to put in this soon (I Hope) to be awesome boat. If I had the funds (and the wifes approval) I would have planned on twin 250s or 300 outboards. Thats not in the cards for this one. Trying to keep formula number one an i/o and keep the feel of an old classic boat with a little modern twist here and there. Not looking to break any speed records but would like to cruise around 25-30 and would be happy with a wot of 45-55 on flat silky windless water. LOL. I have the old tired 302 and the merc 888 outdrive. It could easily be rebuilt. Im thinking maybe a punched out 351 windsor and an alpha 1. Any comments? Suggestions? Pros? Cons? Im open to ideas but just keep in mind I'm not crapping out gold bars every morning….

Re: 1972 Formula 233 Project

454 with a bravo drive? :lol: she would go good with that! really though, a decent 350BS and an alpha would probably be the easiest and most cost effective IMO to give her a bit more 'umph' but not break the bank..

LOL. Its funny you say 454 with a bravo. Thats what I said. She said no but did say once we spit out a kid I could go for it! LOL. Doesn't seem very fair. We all know you're broke after a kid. LOL. A chevy 350 could be a good choice. Cheap parts too.

Re: 1972 Formula 233 Project

I will bet, that your boat will be solid and heavy, once you finish all the infrastructure. I will also bet the 350 will work, but I think you will be disappointed with the performance. If there is a way to get up to the 454, I think you will truly be happier. Resale and just general use will be better with the larger power plant. These are fun choices, but the old adage of "never enough power" might apply here, and you wont have a better time to consider than now. The twin outboards would have been nice too, but that would require all kinds of custom transom work. Price it out and compare, but a 72 boat will be very heavy for a 350 IMO. Nice project and nice work on your end.
