Changing the pitch of the prop will most definitely affect the "final drive" of the boat. This is quote for propellers, but still applies to impellers as well. Got it from this blog
"An engine that does not reach the rated RPM at wide-open-throttle is an “over-propped” condition, resulting in lugging."
You may want to go with a different impeller.

The only time I've been able to get 8000 out of mine is by pitching the stock impeller, which is a 10/21. That was 2 years ago now, but I'm pretty sure I actually lost 1 mph by doing it. Granted, I'm not a professional impeller bender haha.
Currently I'm running a Solas 13/18 with a 4" intake and a Fizzle F1000 and I'm still only spinning 7800 lightly loaded. With 2-3 adults it drops down the 7600-7700. 44-47 mph depending on the load and conditions.
I also have a Solas 14/19 and going by the numbers it should have a lower max rpm, but it doesn't. Honestly I can't tell the difference between the two. That said, I've never ran them back to back on the same day. Maybe I will on my next days off.
There is also a Solas 14/19R which is supposed to mean it's been placed in a pitch block to ensure accuracy. So how did they determine the pitch on the regular 14/19 or 13/18???? I don't have a pitch gauge, but on the bench my 13/18 and 14/19 look the same to my untrained eye.

Pwc muscle is recommending the solas 14/19 pitch would more suit a stock challenger 180. I think I will try one and should bring my rpm up and gain some top speed. I think the 13/17 is more for a lot of add on performance parts as the rpm would come up at the parts are added. Anyone interested in a trade would like a 13/17

That's interesting, my 06 manual says 10/21. The 08's do have a different part number though.

How's the bottom end with that 13/17?
Make sure you get the right 14/19 as there are two different ones. Your boat being a 2008, it should take the SRX-CD, but seeing as it's been modified there's a chance something else might be different. On the boats the impeller shaft changed in 2010 which also changed the impeller. Check out the parts pages and you'll see what I mean.
