    Water Separator Questions

    My engine is a 1985 30 hp Johnson. I have been running an inline fuel filter but was thinking I should maybe put a water separator on instead. I'm not really familiar with what exactly water in the fuel lines does. Do people run water separators on small outboards? Can anyone recommend a...

    Ethanol and engine parts- What needs to be replaced?

    I just recently realized the need to have ethanol safe fuel lines. I was wondering about the lines associated with the fuel pump. Should they be replaced? What other lines, gaskets or valves need to be ethanol safe? I have a 1985 30hp Johnson.
