The original question cites the use of non-ethanol blended fuel in a topside fuel tank, and a concern of water infiltration. Non-ethanol fuel is not subject to the phase separation of ethanol blended fuels. Topside fuel tanks also do not produce the condensation of below deck metal fuel tanks. Your outboard engine contains a fuel filter under the cowl that will perform adequate filtering for engines operating non- ethanol blended fuels. Proper maintenance of this filter is more than adequate to contain any contaminants. However, if you feel the need for an an additional external filter, your should check the capacity of your engines fuel pump to draw fuel through such a filter application, and and that the filter is designed for the fuel flow rate of your engine.

When installed and maintained properly it will not contribute to increased chances of fuel starvation as some have suggested in the past. Needed? No, but a good investment.
