A lot of sharp corners on the tray and gunwale.

Make sure the grate bolts have not popped through the pump shoe.

Set rhe low screws at idle, the popoff will determine where they end up. Tune the top screws for best acceleration. 115 pilots will need low popoff, just make sure it sputters at 1/4 throttle. If it sounds clean its too lean.

Get a Superjet, then you will have a ski that wont back flip.

But the internet says a stroker is always, always, always better.

I bet engine builders stop publishing compression # or at least lower them by a lot. People obsess way too much over something that can vary greatly and still be fine. Use a gauge to find damage by comparing cylinders since they never fail at the same time. If your gauge reads lower than...

Well, volume increases faster than area. For a given rpm, smaller bores can dissipate higher combustion temps. Big bores are fine for freestyle use. I do wonder how difficult it would be to keep one running in a couch. Sooner or later these cylinders will find their way into long hulls that get...

Your small pump will struggle more at low speeds, not so much once underway. The only complaint I have about this and all other PWC related product, is lack of information. It is difficult to decipher buzzwords and testimonials.

Easy to melt 95mm pistons in a two-stroke.

The only OEM hulls light enough to begin with are the old Kawis JS, 300SX or 650SX. Neither will take a side landings but would be fine for back flips.

From 20' they all look the same.

The ad should read. "Here is a trailer for $1000, comes with free scrap jetski." The only trailers to avoid are ones made from box steel tube since they rust from inside.

Too much load.

It will mean nothing unless he is too large for his chosen hull. A big rider on a short hull with low power may find it a chore just to get it moving.

From my limited perspective, it seems like Xscream does a lot of "turn key" boats. There is just not many riders around here that can afford it all at once.

A car doesnt have to plane to go over 15MPH. Carefully consider the size and weight of the hull and rider. Many of the short boats struggle with larger riders.

Maybe for the same reason that they dont make pumps and hulls.

Your question is too vague unless you just want to be like everyone else. What do YOU want to do ???

The easiest way to get an X2 to jump like a typical A/M hull is by simply cutting 12"-18" off the back (depending on your height/weight) and installing SJ pump and inlet. There is no room to move the engine back so make an adapter box for any short Yamaha mid shaft. The X2 has more hull area up...

The rubber elbow helps keep water out. As long as the screens are in place it is safe to run.
