1985 Supra Comp TS6M

From what I can see that repair looks good. It really is an awkward place to work. I've done some wet sanding there and never could get it just like I wanted. Hate to say it, but that epoxy will be harder to sand than what I was doing, so good luck, but regardless, filling the hole was the first objective.

I just took of the swim platform and brackets as I noticed the "transom" is rotten. What has everyone done other than new wood and fibgerlass? Even after replacement, it still seems like a weak design.

i think i used these guys for 1/4" aluminum backing plates- http://www.cut2sizemetals.com/c2sm/custom-cut/

and used big ole washers too.

Also repaired the hole in the hull. Re-fiberglassed the exhaust outlet on the inside, backfilled with PC-11 marine epoxy and 1st coat of marine tex just to seal it all up. Will sand it smooth and go for a second coat. Really awkward spot to get at, did the best I could.

once the platform is on you'll be the only one looking back there.

For the most part, I will probably do a second coat to try and blend it in better plus make sure it is sealed 100% and not even bother sanding it. It is hard enough to get my finger in there I may just have to leave it be! I plan on wetsanding and cutting the gel coat back here so i think once some of the fade and carbon suit are gone off the transom it may blend in a bit better.

Salty87, I'll keep them in mind. I saw what Titan had done and plan on something similar. Was even thinking of 1/8" aluminum plates that are a bit wider on the exterior with longer through bolts to help spread the load. I can't believe this is considered a 'transom'...its just glecoat and a thin layer of glass!

Another update. Sorry for the lack of progress, its been a busy summer so far!

Port side stringers are PB'd in and are feeling very solid. Its not the cleanest job but first time working with the West System products so I thought it wasn't bad! I am amazed at how sturdy the hull is now. When the old stringers were still in, it felt like a wet sponge. That "PB" mix dries tough as nails! Starboard side should be complete next week.

Looking good. Those are some seriously think stringers! Have you thought about how you're going to glass them? I would think that putting a radius on the top edges would make it a lot easier to wrap the glass over them. But then again, it looks like you've already done the inner stringer, so maybe you've figured this out.

Yes and no lol we oversized the stringers because we left the main stringers down the centre of the hull intact and they are " just ok", Only replaced the supports near the cradle. The problem was that I didn't think ahead before I sealed the wood and radius the edge for the glass overtop, I guess seeing all the progress got me a wee bit excited. The plan is to take a sander to them and re seal the edges.

Well guys, we went to the lake for a test float before we put the foam in and glass in the floors.

Couple of small in holes to fill in around the new swim platform support brackets, and some extra fiberglass on the stringers/transom and we should be ready for finishing! Even though there is no gas tank, we are amazed at how high the arse end is sitting in the water. Swim platform used to sit on the water, now it's like 4" higher. The exhaust ports are barely 3/4 submerged!

Sorry for the small photos, iPad photo bucket app! More photos to come. My old man with the boat.

Thanks Villain!

I'm not super pleased with the way my fiberglass Job turned out, the heavy duty matte is hard to work with and soaks up a lot of resin. Got as many air bubbles out as i could. Should I be worried about it separating from the hull? I made sure to resin the hull, then lay the matte then roll out more resin until it would not take anymore .

Could I add some CSM over top for any added structure?

CSM won't make a huge difference in strength, but it will look a lot better and smooth out better.
