In choppy seas fuel can surge back and forwards through the flow transducer. This back and forth motion causes the flow transducer to measure flow readings, which affects the accuracy. The solution is normally to place a fuel resistant one-way valve between the flow transducer and the tank. This problem can also be a symptom of inadequate baffles in the fuel tank allowing fuel to surge in the tank causing pressurised surge in the fuel lines. If you have this problem on an 2100 Series F41 then just wire the unit into the ignition so that when the engine is off the gauge is off.
