58mph out of a ski boat is serious. HP is only part of the picture though- a fast hull will make up for lack of hp. I know of a 17' wooden inboard produced in the early 60's with a stepped hull that would run in the mid 50's with a stock 210hp y-block.

Yeah, that's what I was thinking but had to check. and my I thought you could change the pump direction. http://www.velvetdrive.com/techinfo/V7172/V7172pg1.pdf

why don't you want to change the direction of your motor? Drivers seat on mine is on the right hand side.. Perhaps not ultimate but I don't think it's really noticeable.
