Hey blownschiada, With all the different motor combinations in the boat which motor made most horespower and what was that hp. And how fast did that move the boat? We are trying to figure out what will put us over the 100mph mark we estimate we are making around 650-700hp now turning a A stainless 6100rpm. We want to go to about 900-1000hp and we thought about changing impellars to a double A at the same time but I think that will keep us at the same mph. I have been looking around and it seems if we keep the same impellar in the boat just step up the motor we will only turn the A around 6600-6700rpm but that should push us over 100mph. What do ya think? Thanks for all the info. Dustin
