    Can any Polaris ski run over 8000 plus RPMS?

    I think i read that the pump gets to its maximum amount of output at 8500. Lets say thats true for a moment.
    Then what prop could/would be used? Could a cdi be programmed for it? Would the hull handle the stresses at the thru hull bearing area does the piston speed exceed 4500 feet per second? What kind of horsepower is required to turn 8500?

    Makes me wonder if you took a 6 speed trans and zx-11 motor and a huge seadoo pump and high pitch prop.with lots of.compression (200) if it could work. Hell they turn 14,,000 rpms. Should be able to turn 9000-10000 i would think.

    Could you imagine shifting gears while.riding! Every time ya shift, you get 4 more seconds.of acceleration in each gear! Not sure if that would actually work. Probably cavatate to much.....but...with a huge pump it may work. Just a thought,,

    The real thread is about going to 8500 (the limit before.stuffing). Any thoughts? Im certain i could do 75 on my pro on glass safely. The ski stays planted. I mighth have to wear velcro if i hit a bump at that speed. Hahaha

    my moto marine 785 turned 8250 and my ss 785 turned the same and my matrix from delaughter spun a 7.0 at 9400 out of the whole a few times but consistently turns 8000 rpm's almost any 785 with after market pipes should turn over 8000 without a problem ,my pro 1200 will be set up to turn 8000-8100 all day when done
    Mickeys pretty much stock 785 turns 8000 pretty consistant till it wars up and then still spins at 7950
    I was told 8100 is pretty much the limit if you want it to last
