    you'd probably get it with less gas.

    What was the air temp, water temp, and humidity when you tested?

    You will pick up @ 1-2 mph as your gas level drops from full to Buzzer.

    18.5 gallon tank at 6.5 Lb per gallon = 120 Lbs in front of ski.

    As the fuel level drops the weight drops and allows the bow of ski to come higher out of water. Less hull drag equals faster speed.

    I read on here 70 pounds is just about equal to 1 mph.

    I need to go on a diet (260 without my life jacket).

    That sounds right in this florida heat last week i ran 68.2 with a full tank and my best top speed in this heat is 69.9 so you can lose 1.5 with a full tank

    I went from 66.7 to 66.3 just from heat soak after about 10 runs or so.

    It'll be interesting to see if that still happens with my engine/intercooler cooling kit installed.

    The heat and humidity down here during the summer don't help either.
