if the water cooling line fir the engine has a leak in the tray you can get water from it, more leak with engine running though.

Also Look around the rear area and bond line and pump area for damage or separations, top of tray and any foot holds, missing ride plate or intake grate bolts. If nothing is found you'll prolly have to cut the tray open and defoam it, find and seal the leaks...

It's a basically stock 2015 superjet also which is pretty frustrating. Ride plate intake grate bolts are all there. Think this could have anything to do with the midshaft bearing and seal?

Don't think so, I mean how would water get from the midshaft tube into the tray via a midshaft seal. The mdishaft seal issue would leak water into your engine bay...

Your leak as you've described it is very unusual "poring in from the foam in bulk head"

So it's poring in while floating with the engine off?

If your tray is water logged you can get some dripping leakage from that hole..... but not normally poring

Yeah, I let it sit in the water with the hood off and I can see water pouring in from both sides. I never cut or modified anything in the tray besides the turf

Well that sucks! You can pressure test your cooling tubes or vacuum test them
With a hand held vacuum pump to eliminate those...

can you dig some
Of that foam out and put the garden hose in and add water and see if you can see it leaking out the back while on a work stand or trailer ?

I'll go over the hull again tonight and fill the ski with water to see where it leaks from.

If you pull your ride plate bolts out, does it drip water from the holes? Also, when u pull ski out of water, check for water dripping from around the lip of exhaust tube fitting on the back of the hull.

Welp found the leak! The hull split from the top deck in the back left corner. Not really sure how that happened since it has no glass damage

Alright so I've had my ski hanging vertically nose up for about a month until it stoped dripping and then tail up until it stoped dripping. I believe the tray area is water free now. I found someone somewhere who had a similar problem on an old ski and he drilled and taped in zerk fittings all around the leaky corner. Used a sacrificial grease gun to inject some six10 epoxy. What do you guys think before I start drilling holes
