What pitch prop do you guys recommend for my superjet with the following mods:

200 psi comp
Ported
Case porting and epoxied
Msd enhancer and coil
Carbon reeds
Stock carbs
B pipe mod


Currently it has a 13/17 but i feel like the power isnt immediate like my other ski. I think it has a little cavitation. The wear ring is in good shape so its not that.

I weight 155 lbs

I can't say as I am afraid to ever change from what I have.....but if it helps for comparison....I am a 13/16 cutback 3mm.....stock cone....bored nozzle...and it rips and pulls crazy hard. I friggin love it in waves. LOVE. Non ported 718cc 185psi ported B pipe (I swear opening up that manifold and headpipe makes magic happen!)

But if I have any kind of pump seal failure I can feel it right away....I have to add some silicone in certain areas (AM hull maybe not a perfect seal or I just need a new one).

I tinkered with a hooker 9/15. It is not the same that is for sure.

Anyone care to say what is in front of their 9/15 and what the pump specs are?

Anyone ever compare the 2 back to back?

I assumed he was just a little 7xx with some porting and compression.

I was going off of what prop he has and how he he said it was "OK" but not right...

@MADMAT has the hardest hitting 701 driveline in town. Its niiiice.

Sorry to hijack your thread op, but does any body know the measurements of jetwork's A prop or if its similar to the 9/15 hooker or the concord 13/16 3mm cutback.

This is why I can't believe hookers are better or even can be better.

I would love to see someone build 2 pumps with=results using a hooker against a Solas 13/16-3mm. Then list your cone choice and exit bore.

Is your prop a concord 13/17 repitched to 13/16?

Yes....I barley remember ever hearing the word concord but yes 99% sure.

Definitely a 13/17 repitched and cutback.....stock cone...bored nozzle...
