What prop do I need

[Marcpxrs]

I'm currently running a skat 14/19 and am very happy with it.

I'm getting 76mph gps on a nearly empty tank and 74mph full tank with the mods in my sig.

If I was to go with a solas prop for more top end what would I use?

Im currently sitting at 8550 rpm with the skatty and just want a drop in prop that I don't need to pitch that will have me at the same rpm but higher top speed

15/20 or 15/22r? What's the difference?

The 15/22 is taller.

One of the real pros will have to step up here. Your ride is way beyond my limited scope.

I used to run similar mods on my 08Px with a 15/22r.
I was 80+ mph.

Will a 15/22r drop my rpm tho?

It all depends on what pitch you have it at. Ive been runnin a 15/20R for a while now and i just re-pitch for more or less RPMs/holeshot depending on what time of the year/season it is and what nozzle ring im runnin. My prop could be anything from a 14/21 to a 15/19(just throwing those numbers out there i think mines actually a 15/21.5 right now lol). Just depends on what your ski likes the most given a few factors.

Go with the 15/20R

and also the Lucky 13 adjustable pump cone. With the adjustable pump cone you can fine tune your RPM with seasonal changes and benefit from better hole shot, improved acceleration and increased top speed
