Need info on Kawi driveshaft

[WFO Speedracer]

I don't remeber who did it first but there were several people here converting the Fx1 to a Kawi 650 pump,I think you used a stx900 driveshaft.I need some specs off one of those shafts,I have the length @ 23 1/8 what I need to know is the distance from the front end of the shaft to the start and end of the seal surface area.If anyone here has one and can measure that for me I would appreciate it,thanks.:thinking:

You need a 900 or 1100 ZXI shaft.....STX is too long.

Here's a bunch of info: http://www.x-h2o.com/threads/26040

Actually I could use the extra length if the distance from seal surface to shaft end is the same.This is going on a Thunderjet conversion ski and I can pretty much move the pup to where it will work as I am having to build a pump cavity.

I need some more info on Kawi driveshafts, I have a 650sx shaft which is 23 5/8 in. length, the 750sx shaft is 24 7/16 in. length. The 750 shaft is very close to what I need in length but what I need to know is the distance from the rear end of 750SX shaft to the start of the seal surface, anyone have one laying around they can measure?

I have that chart in the WSM book,it only gives you total lengths on the Kawi shafts.
