I have added the following mods this year and am wondering what prop I should go with. I'm currently running a solas IJK 15-19 which came with the ski. I ride purely flatwater.

Whats all this hooker talk about? What about blowsions "cut back" setup?

Mods that matter:
Riva CDI
200psi head
lightly ported/blueprinted 61x cases
Sport port "freestyle" ported 61x cylinders
Riva red pipe

Go with the 9/15 Hooker. The only time you'll look back is when you question why you didn't buy it sooner. If you're currently using a 15-19, you'll be amazed at the difference! The unfortunate part is you can't really find them used because no one is willing to sell it unless they move to a mag pump. I guess that says a lot about what people think of them.

You are massively over propped, basically stuck in overdrive. Find a Solas "S" 14-17 or a concord 13-17. These are the lowest pitch Solas makes but are still a little too much without modification. The Skat 12-17 swirl is good. I have found that a 10-16 hooker is on the high side for a 701, their 9-15 should work very well. You will be blown away by the power increase over what you have when you get the right prop.

Are impellers like boat props? The higher the pitch, the higher the speed? So a 9-15 will give me better low end?

Kind of... Impellers are much more complicated than a normal boat prop but yes, you will notice a huge improvement in bottom end performance with the 9/15 hooker.
