Sense you brought it up, and sense this thread seems to back on track. Whats the thinking behind the 7/8" shaft ? Is it that its lighter (easier to spin up) or that its smaller and has less drag ? I only ask because the hardware (hardware from a SS boat) that came with my project included a 7/8" shaft. 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.
