Has it ever been done?? Well it’s about to happen.

Sounds like you have a well thought out plan in place. Just a slight piece of advice. Look carefully at the inside of the transom where the set back "bubble" it comes through the transom. See that 1" gap on either side? My advice is to fill it and then glass over it to either side of the stringers back there for much needed and added strength. The general consensus of thought is that the reason these hulls are only rated for 200 HP outboards is that the original construction of the way the bubble is attached through the transom made it unwise to rate the hull for a higher HP engine. Just my 2 cents, but that's what I did with my 96 V21 when I had the deck off it.

I’ve had this plan together for a couple years now just never had the time or money to do it. Time is still hard to come by nowadays but because of that I can finally have a little cash flow to put towards it.

I need to do some cleaning up back there and figure out exactly what’s going on. There’s just globs and globs of the filler material everywhere around the transom. I definitely need to clean it up then look into doing as you say. It’s already this far apart, I might as well get it right now.

Also what bubble are you referring to? I will try to snap a few pics of the transom and maybe you could point out to me what you mean.

Ok so I figured out how to attach thumbs so I guess that's better than nothing. Here's some more of what I'm starting with. First order of business is getting all the foam out and covering her up and possibly putting a dehumidifier in her for a while to try and get her dried out good. Then I guess I'll put some new foam back in her and get the floor sealed up. I've read in a few places that a pressure washer is the best way to get old foam out. Anybody else have any suggestions let me know.

Also I'm planning on stopping by our local fiberglass shop and ordering supplies. I'm thinking about getting 5 gallons of laminating resin and 5 gallons finish resin and a whole bunch of cloth and mat. After I get the floor in and cap supports I may save myself some trouble and take it to my guy and have him chop gun the whole inside. He recently did a boat for a buddy of mine and I guess they put the white gel coat right in the strand and it looks great.

Ok, not sure why but the pics are upside down, but the first ones weren't. Ill figure this out one day.

I call the set back that the engine mounts onto the bubble. Don't know what else to call it so I coined the phrase. Since a V20 has an almost flat transom, the setback on the V21 from the outside looked like a bubble to me.

Anyways, if you look at the inside of the transom where the bubble is attached you'll see that the two pieces (transom and bubble) are not connected very well. There's a gap on the sides. it's that gap that I'm talking about. fill it with filler and then class it all together and that should add some additional strength to the whole transom. It's not necessary, but when I had my deck off and looked it just seemed prudent to do so.

Ok I think I see where you’re referring to. Right now there’s a layer of that hard filler on top of the transom but I hit it with a hammer on the sides and it feels like there is foam under it. Does seem like a very vurnable void. I’ll definitly look into it. I still haven’t confirmed the wood to be completely solid yet. If I grind/cut out the filler on top of the transom and the core seems wet I may be looking into a carbon-core pourable transom and it’d be ideal to seal the top of the transom up to the highest point where it meets the normal transom location and fill the lower transom and those voids at the same time. Very confusing I know haha. Hopefully in the next few days we’ll get some decent weather and I can get into it. Been raining nonstop here.
