i posted this on BBC but i did not get that much feedback, so i am reposting here. 1. In my P4 i have the 30 gallon main tank under the seats and the 2 10 gallon saddle tanks behind that. is there any pros or cons to running with a full main tank and the saddle tanks close to empty or the other way around? or does it work out better with all tanks full? the pros and cons i ask about are are preformance related. 2. my low fuel warning comes on (smartcraft) with about 10-12 gallons still in the main tank(based on my gallons used gauge). is this normal? is there a gauge i should trust more(fuel gauge or fuel used gauge)?3. is it ok to run a tank empty(mostly to varify my readings so i do not end up stuck somewhere) and then switch to the other tanks?it has happened to me before where i was sure i had a fair amount of fuel and the low fuel warning pops up and it keeps me from running where i want because i am worried about getting stuck.thanks for any insight on this

Run your main tank empty first. Performance wise youll be better off just running the saddle tanks, and keep some fuel in your main tank for emergengies. D

Set your individual Smart Craft gauges on percentages and calibrate the one you depend on when you fill your tank from Empty with the SC Gauges. BCB

Once you run your engine out of gas youll have to squeeze the fuel bulb to re-prime the system. Takes about a minute to do.

We would not run it totally dry. It is not good to lean burn the engines.

With gas in the main tank you have more weight forward that can put more boat in the warter (slower) . With more gas in the saddle tank the weight is in the aft side of the boat. My puma feels different (better) using mainly the saddle tanks. I dont know what boat fuel weighs, but Aircraft fuel weighs 6.71 lbs per gallon so moving fuel around can change how it handles, allot. 6.71 X 32= 214.72lbs to move around. I have not ran any tank dry but I do run it down pretty good every once in a while. Gas can and will go bad, so I want to use all my tanks a little to keep it from vasnishing over. My fuel low % is set up the sme way. When I get low I go back and look at the tank so in a tournament I an relate the percentage on the gauge to run time left. When you do this ensure there is extra fuel in the main tank to get back to the ramp. I also look at my RPMs to see how much they effect my fuel comsumption. Good luck Russ.
