Ok thanks for helping so far....and thanks for not beating me up for being a car guy. One more question(well, for now....maybe more). The quote about prop slip got me wondering. How does the drive setup actually work in these here boats? Is it just one speed(one gear ratio) or multiple gears as in a street car transmission? And, on the launch, is it just direct drive or is there some sort of clutch system or what? Basically, what causes the prop slip? Is the slip through the drivetrain....or are we talking slip in the water(like tirespin) before the prop grabs enough water to start pulling the boat along?
Im getting the impression that they dont have more than one gear to work with. Cause, when I relate it to a car...one of these big inchers can be built to make explosive torque at lower speeds and still make 650 horses or better at around 6000rpm. This is the hot ticket in a street car and even if torque is lacking at low speeds....having 3 or more gears to choose from really helps things out. However, if the boat on has one gear, which would be equivaltent to top gear in the car....than I understand much more why its good to be able to rev well and gear these things up GOOD. Even with all that torque a big incher can make, a street car would have plenty of trouble trying to launch in drive! I hope that made sense. Thanks again guys.
