I have a 2005 TR196 Yamaha 0X66 25p tempest plus prop worked by Mark (great job) 6 inch jp running between 2.5 to 2.75 below pad. I think I have motor hieght right. I can only get 66 to 67 mph gps 5600 to 5750 rpm medium load. I want to see 70+ mph. Does anyone have any suggestions? Holeshot is good, no chinewalk problem, good bowlift. Does anyone think a Vmax 25p T1 or a trophy 25 would help? Any sugesstions would be greatly appreciated. john
