what impeller do i need?

[xavix85]

hi all. i know there is a lot threads about it but still don't know what variations to go with.
i have 2008 superjet 717cc with all the add-on mods like ada head,b pipe,vforce,enhancer,single 46sbn and sport port,worx intake grate.
I'm running now solas 13-17 with stock pump.
i have also the option to run the stock 08+ impeller.
or should i get the hooker 9-15 or 10-16?
and of course should i buy the mag pump or its waste of money?

im 190lbs weight if its makes any different.

How does it run with the 13/17, Assuming you have a Concorde. Not a bad prop.

runs pretty good but always happy to make it better. this is the impeller i bought with the ski.

If you want more bottom go with the 9/15. I ran a 10/16 on an 82mm ported 61x and it did good. Got a used 9/15 that was banged up and sent to IMPROS and had pitched to a 9.5/15.5. It seams to work good.

Solas and impros have different pitches for relatively same performance. On a x2, a 10/16 imrpos is similar to a 13/18 solas per dave of imrpos. Not saying to not change props, but just realize a big change in numbers doesnt mean a big change in performance.

Ignore the numbers between brands. That's what I was told. You could do a lot worse than hitting up jetworks and saying you need a prop for that setup. They really know their stuff.

concorde is really good prop for the money they are worth these days...little. very hard to tell diff between it and hooker unless you are making really good power with larger motors. then its worth going to 148 mag and skip the 144 all together

I need a prop for a blaster asap!

I felt the solas 144 mag to be a very small improvement for the money and extra weight. I run a very similar setup to you and found a well tuned stock pump to perform quite well with a various props from 10/16 to 14/19 depending on where you wanted the power. The only place I saw some gains over the stock pump with the mag is in the white wash and the extra vanes straightening the water. I also found gains with the stub cone over stock for low end thrust. Next year i'm going to be trying the 155 pump small motor route and have a 7/15 prop to try, but your pump tunnel also has to be larger to feed the 155
