[QUOTE="PSG-1, post: 292911, member: 6937"] The only way to know about fuel consumption, is to take the GPS on about 10 trips. Vary the throttle from idle, to cruising speed to WOT, try it alone, and then with passengers, try it in swift current/tide vs. no current/tidal movement. Run on some stretches of open-straight water, and then some stretches of winding river and hairpin turns. Start with a full tank, noting exactly how much it takes to completely fill the tank, then, at the end of a trip, re-fill the tank and make a note of how many gallons it took, then average it out with the GPS track and trip log. Doing this will give you an AVERAGE fuel consumption rate. For instance, my jetboat gets about 5 MPG, or, burns approx 3 GPH, at average running speeds. With a 22 gallon capacity, theoretically, I could run about 100-110 miles, or run for about 7 hours before refueling. That's the absolute limit, which I'm not going to try. Because, even with MPG and GPH info, you should always go by the 1/3 rule. 1/3 to go to the destination, 1/3 to return, and 1/3 for reserve. If you operate by this rule, you'll always be on the safe side. I rarely exceed 60 miles for the total distance traveled on any of my outings, because, first off, that's a pretty long boat ride, and second off, I've run out of gas on the water, and paddling sucks! :D [/QUOTE]
