    Gas mileage

    Sooooo, with gas going up again, and $4/gallon a likely prospect for next summer, what kind of gas mileage are you guys seeing on these gprxp's as far a cuising and basic tooling around on the lake?

    Right now I have 4 thirsty 2 strokes, and 3 of them have big carbs. I can swallow a full 13gallon tank in less than 45minutes. Cruising with some peeps is a pain because I am usually the first one on the buzzer. I'm seriously concidering selling off some of my fleet to finance a gprxp.

    It's pretty nice. I can cruise for a few hours on a full tank. Now If I'm on the gas, I can drain 16 in an hour or so... just like any watercraft. This was one of the driving forces in doing the gpr build. I love the 91oct aspect of it too.

    Good deal. Thanks Mark.

    Hey, here's another question- Why do you guys use the rxp gas tank? From the pics on your site and here it appears that the rxp tank doesn't quite fit Is there a way to put the doo sending unit in the yami tank? witch one is bigger?

    The 16 gallon tank of the rxp/t fits pretty nice actually, either forwards or backwards. Backwards works best.

    The problem with putting the fuel sending unit in the GPR (or larger 18gallon XLT tank) is the depth of the RXP unit. The RXP sending unit is expandable, and spring loaded, but only goes so deep in the gpr gas tank. So, if you were trying to make it pick up from the bottom of the tank then you would need to modify the pickup to work. While possible, I'm not going down that road.

    Once it's all installed, you can't tell.

    Spare a thought for us Aussies who are currently paying $5.30/Gallon.
