HELP with my 03 GTX
I recently got me a 03 GTX SC. I added to it a
13/20r riva impeler,
new wear ring
Top-Loader Intake Grate.
I was thinking the ski should do better than factory. But i guess i was wrong its slower it down to 58mph on gps @ 6800. then someone told me to use a diffrent propeller that so i change it again for a 12/20 and guess what it did worst 55mpg on gps @ 6700rpm.
I am schedule to get the SC rebuild this week. Will this help on the RPM
any suggestions on witch impeller to keep i did like the riva 13/20r it feels more aggressive coming out the hole but i can be wrong so please help i don't want to keep putting money to the ski so i go slower the idea of putting $$ is to go faster..
Water conditions where the same both times i test ride the ski since is on a fresh water canal.
Please Help.. r7,600RPM

Well you also have to remember stock internal axnd SC gear on the 185Hp are different than the 215HP SC Going with an X charger and stock internal (Cast Pistons) not such a good idea!..just my .02 cents i've been that route before that's why i bought an RXT in my opinion i believe the prop you have it too tall for the minimal mods you have you should have gone with a 14/17r you must bring the rpms back up
