250 x cavitation fix "please"
i have adv timing and wedge which i really like although when i gas it it cavitates , i thought it was knock from to much timing until i rode a SHO and it did the same thing ,
Will the pump shoe fix this or the pump cone?
Can i ask for peolpe to offer ther opinions only if they had done these mods and noticed a difference.

Before spending money on more parts, first you wanna tell use how many hours are on your ski. Also let us know if you ever sucked a rock or sand.
Personally I think your pump is just due for a good service from Impros and your back to normal unless this is been an issue from day one you owned the ski.

Whats an impros service on a pump cost now a days? Would it be cheaper to replace the pump? I think the pump is 230ish

My ski never cavitated untill I did the timing advance.
It pulls much harder on the bottom end and I think (in my case) this is the cause of the cavitation. Mine doesn't cavitate a lot just a split second on takeoff. If yours is cavitating a lot, it's probably the pump or prop. If it's just a little, I'd say it's the timing advance. I know of several other people
who have done the timing advance and have had a slight cavitation out
of the hole like mine.

If your cavitating off the bottom after the Timing mod then send the prop to Dave at Impros. Tell him to pitch it to Skips specs. He will know what to do. The prop will grab off the bottom and not effect the top. Out of respect to Dave and my work the pitch will not be openly shared but Dave can easily and cheaply pitch and tune the prop for ya.
