    Wave jumping 03 gp1300r

    Well, we were out last week doing some wave jumping, ( had about 10' whitecaps so it was pretty easy to get good air ) had a ball, burnt a full tank of gas. Anyways, I nocticed sometimes if I landed pretty much strait up that my watercraft would bog out for a second. I had no water on board so I don't know what's causing it. Any ideas guys? Is this normal? On a different note, I got to sail my cousins new RXTX. Really good holeshot, but besides that, it didn't seem that powerful, (but it is a big machine). One thing I did notice was at wot, it would bowsearch from side to side, didn't give you a very cofident feel, thou it never hooked or anything. This was the first time I rode A three seater that large, so maybe it's just because of the size of the machine. I do know I would't give up my gpr for it thou. For eash to his own I guess. Later, Donald

    cant help with your bogging problem, but the rxt that i have rode seemed to wander at wot, so i guess its just the way they are designed

    The bog is due to reversion in the pump causing a temporary stagnant water flow. When you land on the tail, water is forced up into the pump the wrong way and it causes the ski to bog a bit until the flow is re-established.

    In non-technical terms - yes, the ski will hesitate for a second.

    Also wwhen you jump your gas is sloshing around in the tank and your not getting good fuel pressure, and probably sucking air... I jump my GPR a whole lot and it does the same thing... Im adding foam into the tank in the next few days... Ill let you know if it makes a difference

    So it sounds comon then. Nobiggy anyways, just was curious and I was thinking that it would pop out of the water alot quicker if it didn't bog. Donald

    Just a thought but is the cat still in (if they came with them there)and does anyone think it could be the slant switch?

    The first several years of FI GPR's had alot of slant switch problems. Yamaha redesigned them in the later years, if I remember correctly.
