What's the length of an OEM Square Nose Drive shaft?

Does anyone know?

I just pulled the pump out of my 90 the other day. I can measure it for you tomorrow morning if you like.

Please do.

Thanks,

Eric.

Well, from the splined end of the driveshaft to where the stator veins start is 22 1/8".

Same length, but on the 650 the short shaft has smaller diameter threads.
We found that out the hard way this past weekend. We needed to replace a coupler that was on a short shaft from a 90SJ...no problem there are probably 6 stock couplers sitting around the shop because of all the drive/short shafts that we have stripped lately...but all from skis with 701's stock. And that **** just don't fit. The 701's have larger diameter coupler threads.
