    Looking for GPS #'s for stock GTI, GTX (2007)

    Hi there,

    Forgive me for the Newbie post. I am looking for some stock GPS#'s for the late model GTI, GTX's from Seadoo, preferably with specifics. (like fuel load, rider weight etc).

    I did a search on the various forums, but for this forum (the best I've come across for 4 stroke doo info) GPS is too short to be accepted by the search engine.

    The reason is:
    I currently own and ride a Yamaha GP800 (old school) with a couple of mild RIVA/Protec mods, & cutback Solas prop. It has great holeshot and tops out around 56-57mph GPS the last time I checked (I'm 185lbs). (fresh engine seals last season). The literature says it's 490lbs dry, and 120ish HP.

    My inlaws want to buy 2 new PWC's, and are looking at the lower end of the models. I just want to know that I won't be going to alot slower boat. I haven't ridden a late model seadoo before, but from what I see on the lake, they will have a much smoother ride in light chop.

    The 2007 'doos that he is looking at are:

    GTI -130hp
    GTI SE - 155hp
    GTX - 155hp - slightly larger hull.

    If my fatherinlaw goes ahead with the PWC purchase, I'll have to sell my GP800 as there isn't enough room at the cottage for 3 PWC lifts, plus the other boat paraphenelia....

    the GTI SE 155 HP would be more playful, accelerate better, and handle better, just be an overall more "fun factor" type of machine of the 3 that you listed.... my only complaint is Seadoo's "cheap" looking color scheme they use on the GTIs

    Thanks for the answers thus far (and the welcome from the Site Admin - boy I feel honoured!)

    I'm kinda torn about getting the new ski. I love(d) my GP800, and have around 215hrs on it. I spent $800cdn last year solving a slight lean / air leak situation, and it still runs pretty good. I liked that it was 'light' and if u were lucky, you could still catch a bit of air even on inland lakes. It still has a few good years left in 'er.

    I hope to keep it in the family, and am trying to sell it to my brother-in-laws, as my parents also have a cottage on the same lake (Lake Muskoka).

    Having two 3seaters would have it's advantages as well. We know have 2 kids, (18month old and 4 yr old), and to be able to take short trips around the lake would be great fun.

    Outta curiousity, the 215hp models... do the 2007 have retard timing options if u use regular gas? Would that drop the power output to 185hp?

    I think if you don't go with a 215 HP unit you will regret it.

    This units do have a knock sensor that will detect knock and retard timing, but it is recommended you use at least 91 octane fuel.

    Welcome to the forum.

    I purchased 2 '06 GTI's last summer. No matter what the load or conditions, calm to slight chop, it seemed to run dead on 53. My wife & I even raced several times, she weighs 115 & I'm 190, and they were dead even. These #'s were GPS and we only ride in fresh water.

    Even tested a '06 GTI SE, same motor for '06, and posted a 53.5. You could probably squeeze off a 54 or 54.5 with a bar of fuel and a Superman run but seems 53 is the magic #.

    Now for the kicker, the GTI was just too slow for me so I sold it 3 mos later and purchased a '06 RXP.

    Good Luck!
