Sorry i had to re-boot...
For about 3 or 4 weeks now Mark and I have been playing around with get this ..An RXT driveshaft in a GTX with an RXP wear ring and RXP impeller with the GTX pump...(you might have to read that twice)...Initial results were SICK to say the least...ZERO cavitation and I was smoking stage one RXP's out of the hole!! Well we have played with about 20 different pitch combos and have figured out....Well I should say Mark has a few of them written down in a little black book ( for some reason he will not let me see) what pitches seem to work for top speed and what works for holeshot...Top speed was 74 mph and STUPID holeshot...If you want to sacrifice some top speed then you get better holeshot...But the awsome part of all this is the price!!..driveshafts are pretty cheap...as are wear rings...you just have to find someone with an RXP that is willing to sell you thier old prop ( if they have switched to solas) I presently have the stock camshaft and the non updated ecu...so I can squeeze about 24 more hp out of my boat before I have to slip into the Engine Manegment System that Mark is selling...So I will let you guys know within a few weeks what the extra 24 hp will do...I am hoping to go over the 75 mph mark...If I don't I will be supprised...

Hell, I was kinda sleepy when I logged on tonight only until I read your post. Now that is awesome and great info, thanks!!! OK Jerry, where is that spare impeller for the RXP that you have just laying around for me??

there is a difference between these parts. I can understand the impeller and length of drive shaft, but everything else sould be the same?
