When following the steps below, run only ONE engine — the 

engine connected to the fuel flow. That is the only way to accurately 

calculate how much fuel passed through the fuel flow. Also, make 

sure the fuel remaining source has been set to Eng/FFlow.

6. Take your boat out, but run only ONE engine — the engine 

connected to the fuel flow. Burn at least 5 gallons of fuel, then fill up 

the tank again, noting how much fuel was added to the tank. Check the 

Fuel Manager page for the fuel used figure calculated by the LMF-400.    
7. Compare the amount of fuel added when you filled up the tank with 

the LMF-400 Fuel Used figure. If the difference between these two 

numbers is greater than 3 percent, you need to recalibrate the unit.  
NOTE:  

If the difference between the LMF-400 fuel used figure and the 

amount of fuel you actually added to the tank is less than 3 

percent, do not recalibrate the EP-10 Fuel Flow.
