Freestyle Impeller question

[Goober]

So i started stripping my square down to get it ready to put into a RN hull, When i pulled the pump assembly i wanted to figure out what impellar i have. I dont have a prop wrench so i didnt try taking it off. But when i look down into it i see An icon that looks like an A with like an S through it after that SO. So its a solas impellar. i see the letters YB- -1 and 14 18. So Whats it good for?? The guy i bought the ski from didnt know what impellar was in it. I am going to want to try doing flatwater freestyle, Motor is a 701 with B pipe/Msd enhancer/dual 44's/Ada head with 33cc domes/ 185 psi/and the owner thought the previous owner did some port work but cant confirm that.

I'm going to venture a guess that it's a 14/18. Are leading edges straight or curved? I'm betting straight. If it's a straight blade 14/18, you'll see notice a night and day difference if you go to a 9/15 hooker from impros.

Is the leading edge following the water flow right? Either way straight.
So i was wondering what does a solas 14/18 sell for nowadays? Apparently i have 2 of them, one in my superjet and 1 in my old waverunner 3 pump.

(Edited first post 185 psi)

Yep, Goob, that prop is a rec/racer prop.

Grab a 9/15 Hooker.
