    Safety Mods. . .

    Hey everyone, I'm new to the forum and to modifying waverunners, and I would like to know which modifications I should do first. I've been doing alot of reading and searching on the forum, and noticed there are a few unsafe parts on the GPRs. These are the things I would like to take care of first, before worrying about any speed or performance parts. The things that concern me the most are the OEM plastic nozzle, stock intake grate, and pump tunnel. I know R&D and Riva make tons of stuff for these skis, but I don't know what I should buy. All I am looking to do is make sure my ski doesn't break on me out in open water. I do alot of ocean riding and wave jumping, and it definitely puts alot of stress on my ski...(especially on the parts I mentioned)

    If anyone could please help guide me in the right direction on what to get, and what to stay away from, I would really appreciate it. As I stated earlier, I'm new to all of this, so please excuse me if I sound dumb in any way.

    Thanks!!~

    first mods to do saftey wise are

    replace grate with a r&d 1200 grate.

    reinforce pump tunnel

    get the recent throttle cable recall done by a authorised agent ( its free)

    replacing the steering nozzle is not a bad idea either, there are good reports on using the SHO nozzle for this application and over time the stock plastic one will breakdown and finally give way.

    You can get all of those parts from the greenhulk online store located here
    http://www.pwc-performance.com/

    use the coupon code greenhulk for a 10% discount.

    that should address the major things that are present but i am sure the guys will probably chip in with other suggestions.

    _izz0, when you say "r&d 1200 grate" do you mean one that's made for a GP1200?

    Replace the Catalytic Convertor also with a D-Plate. the Cat-Cons have been known to break apart in the exhaust

    A 1200 grate was manufactured for the GP1200r. The GP1300r uses the same. This particular part is only 4 bolts. Use a thread sealer for this.

    The D-plate is an easy upgrade but you just have to be patient with getting the pipe in and out of the hull. Use a thread locker for this.

    The nozzle is an easy upgrate as well. Just be sure to use the stand-offs that are currently on the plastic nozzle, they allow for proper torque without binding the nozzle. Use a thread sealer for this.

    Download the repair manual and use it as a guide for torque specs and order of removal. http://greenhulk.net/forums/showthread.php?t=9546

    The tunnel reinforcement is the trickiest of them all but you can find all the right information here: http://greenhulk.net/forums/showthread.php?t=49610

    There are plenty of helpfull people on this site to guide you with the project if you decide to take it on.

    Nothing listed here should void your warranty.

    But, spend too much time on this site and that warranty will be a thing of the past.
