Blaster Stripped shafts

[SQUARE JOEL!!!]

Third set that's stripped! New shafts and pump/midshaft rebuilt, d/s end greased, new orings in midshaft, good shaft overlay. Alignment was done to a gnat's azz. Other than possible hull/bulkhead flex, motor mount flex, or excessive stock coupler runout, other possibilities for these shafts to only last a couple of hours?

Good question, I'd have to ask the owner. Both shafts and rebuild kits came from JetManiac

Those look to be underlapped(underengaged) by almost all of the spline area. You can see where the orings from back of midshaft are making 2 sets of lines way down on the splines. They are supposed to ride in front of the splines about 3/16".

Also the splines are only stripped on the very end of the driveshaft.

Good call Chris! Midshaft had 20mm out the back....hmmm

I would make sure the 20mm dimension matches the midshaft length used just in case you ended up with a shorter one. I install the pump and driveshaft first and set the midshaft to the driveshaft to guarantee full engagement with 10-12mm of end play max.

10-12 mm end play??

10-12mm before the shaft bottoms out in the midshaft.
