Super Jet Water in sides of tray?

[paczowski123]

Earlier today while pullin my 94 SN SJ out of my truck I noticed the sound of water sloshing around in the sides of the tray on my ski. It sounds like its trapped along the side rails has anyone experienced this and will it
Eventually come out? Is there any way to get it out? My ski took on quite a but of water yesterday so I'm assuming its from that?

Your tray is leaking and foam is wet. They all do that. It's a Superjet thing. You can cut the tray open and refoam it. Or just drill some drain holes an drain it after each ride.

The second suggestion is much easier/simpler.

I see, do I put plugs in these holes or what? Anywhere I can see some examples or a thread on that?

It's a drain and a plug in one

I like that eBay plug, but are u saying you just have a hole drilled and a 10mm screwed in it? I have seen some where people use a nursery and screw a bolt in with an o ring

So if the water has made it's way into my tray does it's an the foam is water logged? Like is the foam highly absorbent, or is it more of an over time type thing where continuous leaking causes it to be water logged? My ski doesn't ever really get water in there and it's never happened other than this time since my ski partially sunk from my stupidity

 

[BruceSki]

I find the Squarenose foam absorbs less on the bottom tray than the RN. I could be nuts but its my experience.

 

[paczowski123]

Well hopefully that's the case, it would make me feel a lot better about the situation and not regret doing 2 fire hydrants in a row and almost sinking my ski if I was not close enough to shore to pull it in before it went down.

dont worry...stock superjet hulls wont sink. The gunwales will stick up and inch or so. I you can hear water sloshing around I'd run some drain plugs for now. sounds like a lot is in there

If its waterlogged enough, stock Superjets absolutely will sink. I've seen it happen to three of them.

I just noticed that mine is water-logged as well...went to load it on the trailer and grabbed it in middle only to have it tip backwards in our hands. I just dont know if I want to start the summer off by gutting my sled..this rain doesnt seem to want to stop in the northeast.

About how much time to cut and refoam this project? I am thinking that for now I should just drain it but are most people not installing drain plugs in the rear??

 

[txsuperjetfreak96]

I think it would depend on the person u could probaly do it in a weekend but reality prob spanned over a week, depending on how much spare time u have with work and all

If you do the plugs, how much of the water will drain out of the foam? Will it become water logged again as soon as you put it back in the water?

I drilled holes in my old SN and drained about 1/2 cup of water out of each side. I then cut into the hull and defoamed it. I collected all the wet foam into a garbage bag and it weighed in at 32lbs. If the foam itself weighs 4 lbs then that leaves 29lbs for water trapped within.

The bag sat in my shop for a month and the foam didn't give up very much water at all so it's a nice thought but the only way to rid yourself of waterlogged foam is to pull it all out and replace it.

 

[txsuperjetfreak96]

Idk since its completely water logged even with drain plugs dnt think enough air would get to it, i recently tried an air test on my tray through drain plugs the 2 part foam i put on top of my polystyrene foam seeped through to the bottom of the hull i couldnt even get any air to push through the 2 part foam

Just adding plugs isnt going to do anything. You're going to remain waterlogged, possibly with 20+ lbs of water. A fraction of what's in your tray will drip out, and refill as fast as it did next time you're in the water.

If you're serious about getting the water out, you need to open the tray and refoam with something other than expanding urethane, then add plugs.

I just cut mine open to lower the tray and fix the shoddy foothold install that the previous owner installed.

I drilled those two drain holes, used the air compressor in there and blasted out all the water I could. It was probably a good half gallon. then I proceeded to fiberglass right back over the foam a few days later once everything dried enough. I've done three tray refoams and I can tell you the labor involved is not worth the results at all. Foam is also way stronger than the flimsy stock hull and helps keep strength in the rear of the boat where you land from who knows how high up.

It's hard to say. I refoamed by tray with EPP foam and pulled probably 15 or 20 pounds of waterlogged foam out. Adding the drains was key. The ski ride's like a totally different boat now that there is no water in there. I only weigh 150 pounds, so the loss of 20 pounds of water was super noticeable when gone.
