what prop for my GTX
bought a GTX hull for offshore racing, I'm goind to put the mods I had from the rxp into the gtx.
What prop do you think I should get? I can have a 15/19 or a 13/18 3 blade skat trak.
Any other recommandation will be appreciated.

What engine, driveshaft wear ring size, sipercharger and ext intercooler are you running? Stock 185 hp is a 12/20. Modded 185 with 185 driveshaft is 13/20. 215+ driveshaft 14/19. 215+ ddriveshaft with sc and ext inc is 15/20.

depends on the weather -- cool day 74 to 75 -with less then a half a tank of fuel and empty cargo hold ---- hot day and full around 72 -- cool being a dry day and in the low 70's --- hot being like now upper 90's and humid as hell my ski being a 215 hp and eric at speedfreaks was the guy who recomended and modded my impeller -- it was a 15/20 before he reworked it and put the back set on it -- he did a fantastic job

Anyway, I would try the 15/20 skat to see what it does, but I am guessing you will want to try the 15/20 4 blade...If you send it to Erik (Speedfreeks), he will pitch it to a 12 on the leading edge, so there's something else to think about.

Exactly... Try the 3 blade first before you buy anything
