Resealing platform brackets and pitots - tips?

Not a CC (though I almost bought one before I found this boat) but asking here since you guys seem to be the most active forum for restoration and other mechanical work. One of my platform brackets was leaking so I pulled all three as well as each pitot. When i pulled the center bracket the lower backing piece, a square of stainless threaded in center (lower somewhat shiny piece in pic) tore off the transom. It has some sort of sealant between it and the transom wood and two screws barely biting into it. How should I reattach this piece? Not sure I can screw it back down unless I pull the tank and cut the floor a bit as access is very tight in the bilge and through that small hole. I can smear some 4200 on it and hold it with a wrench while tightening though. Is this sufficient?

Excuse teh dirty transom, it has since been compounded and polished while it's all clear and accessible.




How should I seal these up when reinstalling? 4200 on backside of bracket and how do I ensure the through bolts are sealed? Put 4200 in the hole or a bead around each hole?

Installing a flow through style pitot in place of the original which plugs constantly on the murky river. Just 4200 on the threads of the screws? There was no sealant used on these when I took them off. One side was dry, the other a bit wet but the screws still bite and tighten up. I'll reseal where each hose went though too.

Thanks for any advice. I don't want to do this again, at least not until whenever it comes down to a full restoration. For now I'd be happy with a dry bilge.

Bonus points if anyone can guess the model?

Yes the plate is threaded. It's a 2"x2"x1/2" stainless square. Had a small hole drilled to either side of the main 3/8" threaded hole which had small screws threaded into the transom wood. There are 6 bracket bolts and 5 of these squares. The 6th bolt threads into the bracket pictures which comes off the lift ring. Seems to me it would have been better to have one plate large enough to cover both platform bracket bolts on the outer brackets and for the center have the lift ring brace long enough that both bolts thread into it. Penny pinchers I guess.

Don't know my supras very well... Pirata a real model? Bravura is the one I remember being larger than the comp ts6m.

These guys will point you straight on the 4200/5200.

Got it all sealed up and back together. Used plenty of 4200 on everything, particularly around through bolts and on threads of screws directly into transom wood for the speedometer parts.

Should be sealed up well, hopefully no more leaks. Unfortunately part of the transom is wet so it'll eventually need to be redone. Maybe a winter project to rip that apart and redo it with composite backing since it seems reasonably accessible if I pull the tank. Been wanting to replace the rudder and port anyhow. In that case glad I used 4200 and not 5200. I used 5200 to seal the PP paddlewheel a few years ago, don't expect I'd ever need to remove that.

Boat is a Saltare. Pirata was a good guess, identical aside from windshield and open/closed bow. I expected to hear SunSport, the seemingly more common open bow large Supra.
