    F/I vs. carb 1200 vs 1300 hull

    I have been thinking about upgradeing to an 05 from my 01 GPR with the1300 and upgraded pump and extention

    I was wanting opinnion's on how Fuel injection with the controler and advanced key way compares to stock rejetted carbs and an advent ignition?

    also about how much speed gain are we seeing from the lighter 1300 hull?
    does it ride lighter in the water or have any noticeable handling difference?

    sure would be cheaper just to upgrade the 1200 motor

    it is hard to say what difference the lighter hull makes - that is pretty subjective - for sure it will help acceleration - I have never seen anything on how much weight effects top speed

    The april issue of personal watercraft has a big article on weight reduction - I haven't read the article yet

    I only know of one 80+ EFI boat - so I think there are more skis with carbs above 80

    thank for the feed back Philip but to clarify my 01 is a 1300 with 05/06 pump & advent and a ton of other stuff, I am trying to figure out if there would be any benafit to upgrade or just enjoy what I have

    in that case it is easy, just enjoy what you have

    as it sits right now an EFI ski would probably be slower

    I'm not sure that will be the case for long.

    how fast?
    its in pieces I got my cylinders from lowell two weeks ago and don't have it together, work has been horrible/busy this last month.
    I know of a 05 that might be for sale with seven hour on it and thought if there was any great benafits I would maybe buy it and put my motor in it and use the EFI v/s my 01's carbs

    There are going to be a few fast (80+) EFI boats at the BUG
