How does my boost look -won't hit max rpm Candoo snapshot
Bought a pair of 2013 GTX 260 IS LTD's with around 68 hours on them. One runs great , this one will only hit 7500 rpm max and around 62mph. I have done the following:
comp test (124, 122, 124 hot)
swapped coils from perfect performing machine
new plugs, new battery (was not great)
pressure test intercooler - held 30 psi for 2 hours perfect
Impeller and wear ring look like new
Do I have a boost issue? Or should I be looking at a dragging IBR or pump bearings or something?

It looks you're only making about 7psi of boost, it should be around 10 so you're missing some for sure.

I'm at sea level so looking about 8 psi at 7500... seems if it could spin the charger to 8100, I'd get a couple more psi. Someone suggested checking the fuel pump. I think I'll check SC slip and fuel pump. maybe not in that order.

Oh yeah didn't notice the RPM, was just looking at throttle position. RPM vs boost looks in line.
Yes it could be bad clutch slip or a small boost leak.
SC is a bit of a chicken or the egg, which came first. You need RPM to spin the SC to gain boost but you need boost to spin higher RPM. Everything has to be spot on to gain RPM and boost together.

Boost leak, or slipping supercharger clutch. When is the last time the supercharger has been rebuilt?

Send it to Jerry. You won't have to wonder if it is done correctly.

Don't pay too much! I would be happy to handle the rebuild for you at half the price your dealer will charge. Here's the link to my rebuild service in the GreenHulk Store.

I only use genuine Sea Doo rebuild kits and my turn around time is one day.
