Now that I have a new power head on the old toon I am bringing her to Florida. She has always been a fresh water boat so never had to deal with salt water before. I have seen on some pontoons they have a salt water package including something they add to the toons to keep them from oxidizing I assume. Will I need these if so what are they? I assume when I use it each time I should flush the engine and give it a good wash down. Anything else? I all ready purchased hot maps for the Humminbird so all set for charts. Thanks in advance.
