    Styrofoam

    Is the styrofoam in the back of the GPR really necessary?

    It would only add buoyancy if the ski was actually sinking, so it must just be a safety measure to keep the ski from sinking completely if the hull filled with water.

    Anybody remove it? Any ill effects?

    you have to remove it for a conversion...

    why are you wanting to remove it? Just because?

    with the high flying riding you do it would be a good idea to keep as much of it as possible

    it would be easier to put it back if you cut the pieces in half so they will fit in easier

    styrofoam

    it,s a bitch to do ff or pump reinforcement with it there but put it back once those mods are finished skis are known for there buoyancy for that reason

    How much does the foam really weigh?

    How is a few pounds of flotation foam in the rear anything but a good thing to have?

    Towing your flooded hull back to the dock is one thing. Raising a sunken ski from the bottom (because it didn't float) is another thing entirely.

    More than a few PWC riders have been thankful their machine didn't sink when something went wrong.

    Leaving the drain plug accidentally out is one way, but there are many other ways for a PWC to fill with water unexpectedly.

    It's not that it is heavy - it is falling apart. I'll keep what's left of it in there, I guess.

    Or maybe I could use some of that expanding foam insulation instead? That would seal up the back end pretty well and add buoyancy. Just in the seams - I'm not going to fill the rear of the ski with foam.

    It was a joke about weight reduction......................

    The styrofoam I have taken is the piece's that are in the way while working on the exhaust, jetworks, tunnel reinforcement and also when i relocate the battery. I have not completely taken out every single piece. I have had the displeasure of bringing in a sunken 650x from the middle of the bay once and I try to forget about that day.

    i was told GPR hulls don't sink to the bottom due to the foam in the hull itself.

    Keep in mind yes i had my boat floating in Tennessee , but i do have foam in the front of it. Um I also do not have an extra hull floating around to cut out a cross section. So it is one of those " I heard that " type things..
