May take my boat down the ICW to Florida next winter. Currently, it's fresh water cooled. Once I get there, I will be 17 miles up the Calusahatchee. From what I have been told this area is very low in salt water content. Would it be detrimental to the risers etc. Also, I just thought about the A/C and head. All fresh water handled. Not sure if this sounds like a good idea or not. Any comments? Would take it back up north in the spring.
