    Ethanol treatment

    Go compare what $ you have in to more late model used or new boats and you will feel better... given the age of the boat and the semi obsolescence of Ford in the marine environment you had some headwinds.

    Ethanol treatment

    You will have no issues with ethanol as long as your fuel lines fuel pump and carb internal parts are modern ( aka recent carb kit , new hoses) and you burn through the gas reasonably quickly. At end of season treat it with stabil and you will be fine.
