I'm running a 05 202 with a 225HPDI turning a 27T1 on a 15 inch rapid jack. I'm not real sure how to measure for pad height but I can tell u that the motor is mounted in the second hole from the top and the plate is up 1 3/4. I,m turning the 27T1 at 5900 wot, and the air temp. doesn't seem to make a difference. Water pressure is around 24-27 psi. The fastest I can get on GPS is 76.8 to 77.6 with tourney load and two people. I was expecting more or is this about the best?? Any help would be great.
