    2002 GP 1200r exploded

    Hey guys...long time lurker first time poster.

    Was out on the water today on a boat and we had 2 2002 gp 1200rs that we were runing through the day. At one point one person was on each ski idling then one exploded. Seat shot off throw a 240lb guy at least 6 feet and the hull crack in the all over most damaged in the front and a hole in the back. Luckily the guy only had a gash on his leg that was stitched up

    Any idea why the hell this would have happened? Skis were filled earlier in the day and fumes were aired out

    An explosion requires fuel fumes, air and an ignition source.

    Will somebody be doing an investigation regarding the actual causes?

    Even with gasoline fumes inside the hull there is supposed to be protection against ignition sources.

    With the exception of the battery cables and starter motor, all PWC electrical is supposed to be sealed to explosion proof spec. That means even if a connection arcs internally there is rubber or plastic enclosure to prevent the sparks from touching the air inside the hull.

    And the engine air intake should have a flame arrestor. That metal mesh on the air intake is intended to prevent an engine backfire from igniting fumes inside the hull.

    Has this machine been modified? No flame arrestor, or perhaps wiring changes?

    My guess is that the battery cable connections were loose or corroded at one or more ends, allowing electric sparks inside the hull. This is one reason why it is critical that battery cables (both ends of each cable) and battery post connections be 100% solid, tight and not able to vibrate loose.

    What do you mean when you say the hull was aired out after refueling?

    yes, the nj state police will be investigating what caused the explosion.

    no, the ski hasn't been modified.

    aired out - seat taken off and front hatch opened for a few minutes to let any fumes out

    Damn. Could have been much worse I suppose. What part of jersey? I'm near AC and don't hear anything about it.
