RXT-X power upgrade options....
The next step for my ski is to increase the power output. My budget is $1500. I would like to add to the overall engine performance. I ride about 90% river with plenty of chop, wind, wake. The prop is stock with some minor bending for rpm's.
What would you spend my money on?

RIVA X charger upgrade and 50lb injectors. Prop work.

Thanks, would a rrfpr be a better option instead of larger injectors?

Not really. The best set up would be the 50's and a RRFPR. To keep it around 1500.00. You will be close with the X-upgrade, 50's, RRFPR and a Solas prop. The prop will need to be repitched to your mods for best results.

I should probably have my SC rebuilt and upgraded with Riva washers at the time the wheel and cover are installed. There are two versions of 50# injectors in the online store, one is Riva Pro Series the other is just listed as a 50# for use with Rotax ECU. Is there a difference other than the price?

Riva X upgrade and a IC relocation kit...leave the OEM 42's just add a RRFPR...

I like the sound of Danny's suggestions but it puts me a bit over the budget. What are the advantages of the IC relocation kit, performance wise? I like the looks of the kit and the obvious advantages regarding easier hull access and the ability to upgrade to a thru hull at a later date. I still need to prop this thing correctly, probably need a 15/22R or stock with some custom bending.

IC relocation advantage, don't know performance wise. You will have to use alot of psi with 42's and RRFPR. And you maybe too lean at idle and off boost. 50's and a RRFPR are easier to work with and set up IMO.
