who is best to tweek prop?
i got good test results this weekend on my GTX SC with mods.
currently has a 12/20.
i got best rpm of 7050 to 7150, lets say 7100.
and a top speed of 63.3, lets say 63.
who can tweek my 12/20 anyone in the jersey/philly area?
or do i have to send it off to impros?
jerry, do you do this, or any other tuners?
i know that my 12/20 was tuned before, it is not a 12/20 anymore, but i dont know the exact pitch cuz i got is used, i know it was bent by PPG.
only reason i am hesitant to send it to impros is cuz i have heard they take a long time to turn around, i am hoping someone can do it local, or faster. dont want to loose more than a week off the water now that it is summer.

send it to Jerry Gaddis aka GreenHulk, I wouldnt let anyone else touch it.
Jerry is the best, hands down!

Send it to Impros. They will ship it back in a couple of days.

sorry all , i meant to say impros, not solas... i will edit in a sec.
my impeller was a 12/20,
then it was bent for a GTX SC that had a ton of mods, by PPG
Rotax Racing ECU
Rotax Racing Intercooler
Rotax Racing Thermostat
Rotax Racing clutch-compete kit
Vortec SC Impeller
Solas 12/20 Impeller-repitched by PPG
Riva-racing open air kit
Racing power exhaust system
Complete Opas removal kit
2004 SC pump upgrade
so i know its too much prop for my simple ski...
all i got is
upgraded 2005 pump w GTX SC wear ring and impeller.
R&D air intake ( the short rear one that goes up by the coolant bottle)
my ski was turning 7650 last fall , all stock.
now its pulling 7100 at 63.3mph, better holeshot and no cavitation
want to get it to 7600 and see what it'll do!!!

unless someone can recommend another upgrade to get me some more power???
ECU upgrade? to a 04 or 05 215 hp unit?
or upgrade my SC? i am doing a rebuild on the SC this fall anyways...
what would be simplest cheapest way to get my rpm's up to 7600 by boosting engine power??
then i wouldnt spend money on tweeking a prop, i would spend it on performance!!!!

Before I bought my ski from my friend who works on skis for a living sent the impeller to Impros. They have had really good luck with them.
