You really need to have the shafts coated, I assume your using chromoly steel thats been normalizied. If so, you still need to heat treat them, then put a surface hardening coating on them. Because it's steel, it will corrode extremely fast and the 6mm bolts will not be able to hold that load. So you can make new pulleys, and go to 8mm, which I think would be beneficial if you don't harden and coat the shaft. But we also found that the typical seal will not live as well on chromoly unless you can find a PTFE type seal. Another reason for the surface treatment.
[QUOTE=Ptufaro;2777602]Hot Pursuit you may have not broken a blower but I bet you have broken just about every other part on the boat.

wondering with all these great sugestions, and the awareness of whipple "knowing" these items, why they were not done previous .....just a thought.
And I have still seen the quads have problems, even late models as of a few months old for what its worth
I do know that our part will not fail, yes i'm sure that will make it find the next weak link, but maybe we only needed alittle more. they did work some of the time, and I dont like the small bolts for the pulleys or the dowel pins but I wanted to make this an easy bolt on upgrade.
