I wasn't planning to use it, just curious about how a race boat can get away with such a small shaft, and what advantage it would have. I cant imaging them running a smaller weaker shaft if there wasn't some kind of advantage to it.
My opinion on the 7/8" shafts were on a factory boat with a few hundred horsepower, and it costs too much to change everything to a larger shaft so its what they have and they try to make it work, thats my opinion aim sure GN7 will tell the rhyme or reason...BOB
