i recently bought a stock sxr impeller, i have a friend who does machining on the side. So i figured we would tackle it if it isnt that hard of a job. i was going to send it to impros but i want to get this ski in the water asap. has anyone done this themselves and may have the specs handy? I haven't removed my stock impeller yet so i cannot do a side to side comparison. any help would be great

Have him machine 6mm off the mating surface and then counter bore the threaded area and equal amount to maintain the same amount of recessed area after the 6mm is removed from the mating surface. If he can't understand what to do from this description, do yourself a favor and send it to Impros.

beauty, thanks!! He'll be able to do that no problem. does the slpine side need to be machined at all? I would be more than willing to send it to impros but being from canada i would prolly be looking at a few weeks turn around time unless i paid out the azz for shipping.

Yes splines are cut too. We do our own and it's not as easy as you think. I tell everyone to send it to Dave at impros and save yourself the trouble.

If its a 650sx standup then use a driveshaft from a 750 SS/XI and you wont have to cut the splines, just a quarter inch off the rear.

Because to make the SXR prop fit in a X2 the drive shaft has to sit in deeper.

Hmm....I've machined about 20 SXR props for 650 pumps and never had this problem. The driveshafts I've used were ZXI and STX shafts and they go all the way in until it hits the internal O-ring (bumper) between the pump shaft and driveshaft. I've never seen the splines be a limiting factor. It must be something specific to the X-2 driveshaft....Thanks for the info.

Yes the question here was how to cut a SXR prop to fit a X2. But also a SX you have to cut the splines back to fit in the hull with the stock shaft.
