My current height is 1 9/16" above the hull. Thats prop shaft dead center. According to the manufacturer there factory set up is 1 3/8's to 1 5/8's so i'm almost dead center. What kind of speed increase can i expect by raising them a bit and how high is to high ? I'm currently spinning 62-6400 rpms 15x32 merc 3 blades @ a WOT of 105.6 ? (lite on fuel and optimum conditions)

Bern, the most important thing in engine height is H2O pressure. The safest is to stay above 15lbs at wide open throttle.

Ryan how much do you adust motor hight for different races?

In the current Doug Wright the motors have been moved once at not again. Some Guys move them up and down but we haven't. If you get them out of whack and loose H2O it cooks a motor quick.

on the x's i'm seeing 5 psi at idle, and 12-18 while running depending on trim etc...
PS- Hey Ryan i put a stop pymt on that check, and am sending Dennis(DPT) down to Corpus with $40. cash

Ryan I guess my question should have been, do you lower the motors for rough water races?. It sounds like you do not

We do not move our motors.

thanks again Ryan...
