    Newbie GP1200R Project

    So I'm 16 years old, and I'm new to PWC's. I'm not new to boating in general, as my dad has had several boats over the years and I have a cottage with waterfront. Anyways, in the winter I bought a 2001 GP1200R from a member on here. I'm using my own money for this project, and my own labor. I'm sure there will be a few Hiccups along the way, but hopefully nothing to major.


    Here is a list of things already done:

    Oil Injection Block Off (Installed by previous owner)
    D Plate + Chip (Installed by previous owner)
    2002+ Mid shaft (just installed yesterday)
    Hydro Turf mats (Installed myself a month or two ago)

    Here is what's being done:

    HO pump with 2" extension
    2" cable extensions by oside bill
    Seal Pump Shoe
    GP800R SS intake grate
    Riva Rideplate with some mods
    Riva Sponsons
    New SS bowhook
    Jet Trim Seat cover
    Aftermarket bars
    Pump reinforcement
    Carb rebuild
    Check to make sure oil injection done properly

    Some other things may be done, depending on how I'm doing on the budget.

    i dont think your going to be able to push an Ho pump very well with a stock 1200 motor. You need to mill the head and rejet the carbs to push the dynafly props. also on a stock 1200 I dont think you need a tunnel reinforcement. The old 1200 hulls were stronger. Let someone else chime in but I would take the money you save on the reinforcement and put it to a milled head and jetting.

    From what I read throughout the forum I should see a 1-3 MPH speed gain. If not I'm going to look into that

    Drive down to Ohio and pick up my ski if your looking for high performance.

    Do you already have all of those parts or is that just the wish list?

    I'm assuming you're taking care of the shoe and installing the new pump now since you've already swapped out the mid shaft and your pump is off. You might want to hold off on the seat cover and wait for a 1300 seat with JT cover on it pops up for sale.

    Yes I Am. I already installed the mid shaft, I have the pump I'm just a waiting the extensions. I actually have a 1300 seat, but being in Canada I'm best off just getting a seat cover. I have some of the parts and some are on my wish list. I do it steps at a time to get a feel for the performance each step of the way.
