    you probably dont have enough power to pull 15-22.

    All the mods,S3 with a 15/22R is a good way, I use it, and works well.

    Last count was 80+, and RPM was nice and high too.

    Try it. Nose cone on as well, do what we all do, mash the threads, and loktite it on...

    Needs serious mods though with all the work on the hull. Get it lifted out of the water more for more speed, and mod the pump as well. Careful work pays off here, believe me.

    ALL THE MODS though, all of 'em.
