All this talk about hull drag and differences between the newer hulls and the earlier hulls.... has anyone tried the Worx 2 Degree Trim wedge ??

on my old '08 kawi 15F, the pump wedge made a difference. even though the stx-f hull rides alot flatter than my 2015 VXR.
i have 12 hours on my VXR and my initial GPS was close to my 15's, but i guarantee my 15f was faster with its 1.5 motor and rpm kit from riva. Not knocking the VXR, i like alot of the features that my 15f didnt have, but i thought it was going to be faster and i can tell you from riding for the past 25 years, that it is not faster.
i am going to drop in the riva filter and ribbon delete and post my speeds before and after.

I have a 2013 VXR, unfortunately the pump bolts are not long enough to support the plastic Venturi nozzle without trim that the VXR has, Im now looking at M10x1.25 threaded 316 stainless rod to make 150mm bolts with nuts tigged on the 150mm pieces so I can run this pump wedge, the VXR nosedives at idle with full fuel. I think the 2 degree wedge will make a good difference across the board.

I made a manual set it once trim with the gpr nozzle. It was ok lol

That way I could use a metal nozzle

I have a 2015 VXR. I just installed the Riva Ride Plate, I was amazed with the results. I always ride with my 8 year old son he sits on the front I sit behind him. Prior to the ride plate fastest top speed I have recorded was 62MPH, today I hit 67MPH with the Rive ride plate installed. Unbelievable.

This is going off the of the speedometer however, thinking about trying a GPS app next time out.

2017 VXR with R&D performance kit (intake grate, Solas 13/19, air filter, reflash, sponsons) and riva ribbondelete mod. Took it out on Lake Mead and had a good amount of holeshot cavitation. Strong mid range, but only hit 62.9. 1/4 tank of gas and smooth conditions, but not glass.

Prop looks good, but the nozzle was off at a noticeable angle (noticed by a friend, I guess my time on my old Kawi 300 tainted my perception on that).

So last year without the ribbon delete and intake grate it was 65mph with very little cavitation if any. . I'm pretty sure I did a poor job installing the intake grate / stock ride plate.

Any advice greatly appreciated.

Still available if someone wants it

I Got some VXR/Yammy Stuff for sale.

-Rotax 16 Vein race pump - By Far the best pump ive used for holeshot and CC racing. Only 1-2MPH slower than stock but will destroy a stock pump around bouys. (same as this one) Includes drive shaft for stock VXR - just drops straight in. I also have added a second cooling line. Was about 4k USD i think from memory - with props about 5k. Accept responsible offers.

-Skat Custom props x 2 (short and long blade)
-Riva adjustable Cam gears
-Stock VXR ECU
