I remember your more gears/speeds transmissions in class 1, they were awesome. I assume that those boats were almost driven like a bull dozer with a hydostatic trans - what I mean is the engine rpm's stayed very constant and you changed gears instead of throttleing???
I don't rememeber very well, but weren't those boats more like today's racing (inshore, closed course) as opposed to the old school open ocean racing???
Again, I don't remember but would those multi-speeds work well if you had to throttle alot?
