Starting the engine with fuel levels below the acceptable standard will likely cause damage to the fuel pump. MasterCraft, working in conjunction with the fuel pumps manufacturer, has determined that on initial (first-time) use, the boat should have a minimum of fifteen (15) gallons of gas. This will prevent fuel starvation in instances of extreme running angles or when fuel sloshes away from the fuel pick-up.
Note that continuous wake surfing port or starboard with low fuel in the tank will starve the pump of fuel and cause it to either seize or overheat and blow fuses. The boat should never be used for wake surfing at less than one-quarter (1/4) tank full of fuel.
CAUTION: Allowing the fuel level in the fuel tank to fall below one-quarter of a tank full may affect the reliability of the fuel pump or result in damage to the fuel pump, which is not covered under warranty.
