SJ power over boat wake

[mthomps]

I think art at jetworks told me more volume through the pump. That it sacrifices a little speed but for low mid gain. Something like that. Told me the same thing about the cone too. Stock cone

I'm half convinced his A prop is in fact a 13/16 3mm cutback. I've never gotten an answer one that

I switched right back to my 13/16 cutback. People have told me I am wrong and I don't get it!!!

What SJ hull are you on? pre-08?

Aftermarket now....but this prop and pump combo and have been on at least a 96, a 2001, and now my Waterdawg Envy.

Remember this whole industry is about fleecing a kid as he passes through the sport. The small hub and large hub Solas Concords work very well once they have been bent to achieve 7000+ rpm. Cones and cutbacks are mainly ways for the pump guys to make more money.

I just sell what is asked for. If they don't know what they're doing, that's not on me. That's why I give honest info on junk that does nothing when others don't, but it's not my job to educate a potential buyer on what I'm selling.

While i have mixed feelings on jetworks, send them an email and tell them what you have, a stock superjet. and you want a nozzle bore and a prop.

Theyll tell you to send in the nozzle and once you pay youll get your crap back fairly quick.

I will say this, once you start engine modding the law of diminishing returns seeps in before you realize it. My driveline is a 61x 701 46mm wet jet motor i put a ported cylinder on with an ada girdled head domed for about 180psi per jug. Lightened flywheel, b piped, ported cylinder, every bell and whistle you can do to a 701.

I miss my 650 6m6 yami with a protech pipe, bored nozzle, and A prop. A few thousand later it was just barely worth all the added hassle

@mthomps et al. What do you think of the performance gains of the "big bore" engines including those made by JetManiac/Blue?
