Didn't take pictures lol that being said here we go.

Did a Edge build for a friend and we needed a waterbox. Of corse after seeing pictures of these things I had to try one out.

Quality: the welding is top notch. The box has nice rolled ends on the inlet and outlet flanges. The baffles have plenty of welding throughout so I doubt we will see any have problems with it coming out. The baffle design looks good for water backflow control.

Features: back to the inlet and outlet flanges. It's hard to get the hoses on which means it will be hard for them to pop off. Definitely no flaw there! The box is small and fit perfect in the rockered nose of the edge. Sits right where it needed to be. It's a very well thought out shape. Contours the hull nicely. I could have put it in with no turf and 1 strap and it wouldn't have moved. The angles of the inlet and outlet were perfect! No hose binding and weird issues. The box sits correct and how it should.

Noise: It had a deep tone and that nice sweet pop everyone is looking for. Not to loud but defffffffinatly not quiet haha. Loud is safe right?

All in all IF I didn't run tnt's in all our skis I would have ordered these boxes for everything.

Finally got a chance to ride my ski this week, I will do my best to describe my findings.
Fitment:
I put mine in my XFT Free-X which is basically a superjet copy so no additional nose rocker. I initially just glued some turf on the bottom and strapped it in but found that my long exhaust hose wouldn't reach. Not doing any thinking for myself I messaged JM who suggested adding some padding under it. I cut some underpadding down into a wedge that was about 2" tall towards the nose and tapered to nothing at the gas tank side of the box. This put it in the straight upright position, my long exhaust hose now reached and it helped the hose clear the corner of the fuel tank easier.
Sound:
I am not going to lie, the box is a good bit louder than stock, that was expected. I feel carbon hulls seem to resonate more and amplify the sound but my ski is pretty loud. I would say it is slightly quieter than the H2O box I had in my Chan and much quieter than the old style Xscream and TDR boxes I have run in the past. I am also running a 2.5? seat in my stinger fitting so not injecting a ton of water into the box. My hull has a built in resonator with water injection so I might play around with running a "T" to that with and adjustable valve so I can find a good balance of noise and power.
Performance: This is probably the most likely question, unfortunately I am running a completely new engine setup from last year and am not able to ride it back to back with a stock box. The ski ran great, extra crispy throttle response and it sounded the part.
Verdict:
Awesome piece, the design is especially good if you have a bunch of nose rocker but is easily tailored to any hull. If you don't ride somewhere that noise is an issue, definitely try it out. If your neighbors raise a stink about the sound, maybe add a bit more water into your stinger.

Or tell your neighbors loud is safe, pulled that card on a guy on the lake that lives by one of the launches we go to. He was totally down with it. Said he never thought of it like that and thanked me for being polite

Anyone have a noise comparison to stock or video of the box in action? Curious to see how it sounds
