I dont think people realize how hard Marty worked on getting the boat to those speeds, it wasnt like he plopped the motor in and went 8.55 @ 127 mph, they were CONSTANTLY testing and trying new ideas.
I agree with Maximus,you gotta have your sh*t togethor to get one going, even with the best motor, you still need to get it set up.
Very true, and I believe his jet pump (from intake to nozzle) was a combination from just about evey mfg out there...
