    just a stubid question.

    I am new to jet ski, thanks to helpful members in this forums, i got to rebuilt my first polaris sl 780 1996 and running strong. I have a stubid question now. I am looking at some high HP jet ski and they only have 2 cylinders where some lower HP jet ski have 3 cylinders like mine. So my question is what is that isn't more cylinders give an engine more HP?

    No......and to make it more interesting more HP doesn't necessarily mean more speed either

    So what are we looking for when we need high top speed?

    Take this one further. Polaris Pro 785, 780ish cc, carburated, 3 cyl, 2 stroke is said to put out over 135hp. My 1800cc, 4 cyl, fuel injected, 4 stroke car...130hp, dynoed 81 whp @ 7200 ft.

    What????? Please elaborate on this some more.

    More HP gives you the ability to make more top speed by using a higher pitched impeller.

    Exactly.....more HP alone may not give you anything. That's my point. It's a fine balance. Its also like saying a 150HP ski cannot be faster than another 215HP ski......I just changed that post - I can see where you got that impression!!

    OK, so you were going along the same lines as i thought.

    More HP doesn't necessarily mean faster without the proper impeller behind it. Got you.

    Thanks for clearing that up.


    You know you can't make simple comments like that without backing it up. You're just going to confuse all the newbs, and people like ME!!!!!
