Other The ScupperBox

[LimitedSlip7]

Having problems with water filling up your lay-down style pipe and getting into your expensive motor? Can't fit a tall waterbox into your hull but still want protection against water intrusion? Don't want to worry about rubber flaps degrading and tearing off? This might be the waterbox for you!

Designed to prevent water from rushing back up your exhaust tube while maintaining a compact size, this waterbox is laser cut and CNC bent from corrosion-resistant 5052 aluminum before being TIG welded. As soon as water starts to flow back into the box, the hinged aluminum flap closes tight against the baffle, significantly limiting flow back into the box while allowing exhaust gasses to flow freely once you're back on the throttle.

Waterbox Backflow Tests:

This video shows a couple of the bench tests performed to simulate hypothetical situations that could cause significant amounts of water to rush back into the exhaust. I used the popular PFP and TNT waterboxes as benchmarks.

Have you done any rpm/speed comparisons between this box and any other boxes?

@Jamo07sj You need this^^

No, just flow testing

Pm sent, real nice work!

I had the opportunity to be a test dummy. This box works and it works very well. No back flow issues at all and I think it may have made a slight power increase.

How loud is this compared to a tnt box?

It's about the same as the PFP box

Nice work, I'd like to give one of these a try!

Didn't run one but got to see the build quality and just like the fuel cells it's is second to none. Love to see you actually got these out for people to actually try and review before rushing it to market unlike 99% of the other guys. nice job and perfect execution!!

I can also have these powdercoated for $20; 30 colors available!

Also, my 4.7 gallon tank will fit with the TNT pipe when used with this waterbox. If you buy any sized tank and a waterbox together, get $20 off!

Seems like reading would answer your question.......

 

[erik mx45]

yeh well its says nothing about what hinged pin is made off !?thats why i asked!so i am to assume the pin is out of the same material?

The flap and hinge are made from 5052 while the pin is made from hard-anodized 6061. The excess oil and carbon deposits from the exhaust also help protect and lubricate the parts. As long as you flush your ski after riding salt, or at least give it a quick blip to clear out the box, you shouldn't have a problem.

If anyone is on the fence about trying one of these, I'll offer a 90 day money back guarantee on this first production run if you aren't 100% satisfied with it! Don't like the sound? Doesn't fit quite the way you want? Not happy with the performance? Just return it! The only stipulation is that it can't be cut up or modified.

I can also modify the inlet/outlet tubes per request for perfect fitment!
