Steve what pump are you running? The HO pump?

[Shibby1485]

yes HO pump

and i have an XLT nozzle and a gpr nozzle.. i think 85mm GPR nozzle and 87mm XLT nozzle

This is going to be a hard one Steve. The prop in my conversion is a 14/18 DF and you dont have the HP that the SC IC 4Tec has.

Do you have any idea what the stock prop in a non SC ski is?

No. He is going to be running a NA 4-Tec at Mudbug since he wont be able to get the turbo set up finished.

Just run a stock prop out of an 05-newer GPR with the 85 nozzle. I have one you can use if needed

arhhh ok sorry didnt realise just thought it must have been a typo

Like Rich said, just run a stock one until you see where your at. Even tho the HP might be close to a stock 2 stroke, the torque curve is most likely very different.

I'll have all my prop bending tools at the bug if you need to go up or down. Everything just fits in the reese hitch.

sweet! ok thanks guys...

i'll throw a stocker in there for now and we'll see how it goes... worst case i'm buying some of you prop benders a beer to get me dialed in
