The filter holds about 1L. That is a lot of water to get by condensation, but not a lot from a doggy fuel supply. If say you manage to take on 1.5L of water with your fuel, you will be trying to run the engine on water after about 1 mile if you burn 1L/mile. You then have to unscrew the filter, empty it, refit, prime, empty......... That is if you have worked out the engine has stopped because of water. At least if you can see water in the bowl you have a clue as to what might have stopped the engine.
On our Yam HPDI (and probably on Outnabouts engine) there is a "water in fuel sensor" inside the engine fuel filter that automatically limits the engine and trips the siren & water warning light on the instruments if there is water contamination, so you should be able to stop and sort the problem out. As we found out - it is a pain to pump all the water in the system out using the primer bulb. At least it helps you work out if your main/deck tank is contaminated - as long as you have good fuel to switch to!
(On the yam gauges the water warning light isnt documented for the RPM gauge, but you can find it under the fuel computer document. If like us you dont have the fuel computer, the warning symbol is on the RPM gague.)
