    Coolant flow thrust mod

    So i have been thinking the pisser is wasted energy. If I enlarge the feed to the discharge of water located at the front of the ski and close the actual discharge hole on the hull could i build more thrust if i routed the discharge below the waterline?

    My opinion would be that it would negate any benefit in drag. I don't see the pisser ever having any thrust worth messing with. But what do i know?

    great idea man but you would then have to mount one on the left side so your ski wouldn't be constantly turning left.

    sounds like you are very bored and on the turps

    Actually i am thinking of tapping my pump shoe and putting 45 elbows to help lift the rear and provide less drag

    I like that idea, you should remove one of the impeller blades too, less drag in the pump

    i was thinking of race taping the shoe laces on my booties down to stop them from flapping around
    this should have the same effect if not more

    Me, personally, eat a lot of beans the night before a top speed run and you can figure the rest out........little extra "air thrust" out the back. I fugure its worth about .001 mph. Much needed on the 250x for more top end. Now if i can figure out how to ignite that extra "air thrust" i would have and afterburner and we would be talking MAJOR speed increase.
