    My shorty waterbox mod

    Here are some pics of my shorty waterbox mod which I decided to do after in the last Tampa meet the rest of the baffles that were left broke. As you can see I used my Riva exhaust tube for the mod. I completely gutted it.

    with that exhaust setup that way you will see a nice acelleration gain but it might scrub off on top end......... should be interesting to see what happens let us know how it works for ya.

    Agreed, with no waterbox you gain tremendous bottom end but I lost on top. I attribute that loss to a timing issue though.

    I think he just needs to tweak the prop a little to get the R's back. He swapped the prop at the same time

    damn... i'm interested to hear how this pans out

    put the old prop back in! see if ur the same speed or slower or what... props and RPMs are so sensitive on these skis, the worst is adding more than 1 mod at a time when it involves a prop.

    its the prop, the w box is not going to hurt him that bad. Like shibby said, if u can put the same prop back in and give her a run. I had the same thing happen to me on that 15/19Skat, it was 4mph slower than my 15/20 you might need to tweak that 15/19.
