    tunnel reinforcement

    ok, so im reading through the forum about some mods and see where a lot of respected people are saying the first thing you should do to a ski is the pump tunnel reinforcement. does this apply to the 2000 gp1200r?

    If you plan on doing a lot of mods and making the ski significantly fast, it's wise to do a pump tunnel mod at some point. When you start shoving enough water through the pump tunnel to move the ski well over 70mph, it really increases the pump tunnel pressures and you can start getting cracks. And the pump tunnel is a bad place to get a leak, you can sink really fast.

    Or you can do a pump pressure relief mod and not worry about it.

    older hulls are stronger than the 03+, but it is recommended like Smitty says if you are modding

    if you are going to say close to stock, at least replace the pump shoe brackets to the 04+ style and maybe seal the shoe... the single style shoe inserts are bad about pulling thru the hull

    The search function will answer all of those questions. In fact, if you scroll down, there are links to old threads under the "similar threads" section.
