    Question ?'s bout Waterbox mod

    Well I followed Jerry's instructions about how to mod your waterbox in the tip of the day section.

    I followed the instructions exactly except I used a 2 1/8 hole saw instead of 2"

    Is this going to cause any problems. Also does this mod increase rpms. i am wondering if I need to bend prop?

    Question

    Awesome. That sounds good. Now what about the rpms. Jerry tuned the prop perfectly for my ski last year. But this year I added thru hull exhaust, RE Blockoffs, and the waterbox mod. How much do i need to increase the pitch Jerry?

    I suggest you run it to see where you are at, get rpm reading, and go from there...
