Just a little bit of info on the 250
This stuff is according to the Service Manual(just got mine today)
Fuel Pressure at idle.....43 psi
Engine speed range......100~8100 rpm
ECU .......Mitsubishi Electric,Digital memory type,with built in IC igniter,sealed with resin
*Fuel Consumption........70 L/h(11.4 US gal/h)@full throttle
*Cruising range.............112 km(90.7 mile)@ full throttle
*this information shown represnts results under controlled conditions, and the information may not be correct under other conditions.
Heres a lil info from me,
There is not a wear ring in the impeller housing, so you may want to save them hard hole shots for when you need them, cause a new housing is $299.00 retail not counting the bearings and all that good stuff.

This is your first Kawasaki?

No I have 2 2002 Ultra 150s, and have had a few others.

From what riders report on the fuel mileage, the "controlled conditions" where Kawi was able to get over 90 miles range on a full tank at WOT must have been run in never never land !! I can see that the shop manual will be full of misprints and inaccurate info just as most of the literature provided by Kawi usually seems to be.

We rode over 60 miles today and I had one bar showing when I pulled it out. I can see 70 or 80 for sure with the R&D extended Fuel pickup.
I did a lot of full throttle blasting too !

The wear ring situation will depend upon lots of stuff, like bearing placement, and runout, vs. engine power and hull weight. I've always had much, much better luck with linerless wear rings. Tried a few of those plastic rings and found they eat up in a hurry. I much prefer a hard liner. Tolerances stay tight longer...as long as your pump bearings don't deflect.
As hard as this craft launches it may be hard on the pump. On the flip side, the fact that the prop doesn't spin, means virtually ZERO prop/w-r burn.

wear pump housing.
Ive been inside of mine, there is a little scoring on it, with just over 7 hours on it, Im going to hold off on the hard hole shots until they are needed!
