I have my 310 DA in fresh water. When I bought it last year, the bottom paint was pretty sad but I opted not to have it painted by the Sea Ray dealer/broker. Of course at fall haul-out, it was sadder and I'm thinking I should probably have this done. But it makes me wonder -- what happens if I kick that can down the road another year? The lake we're on is pretty clean and after haul out the paint looked sad, but we didn't have a lot of bad growth and you can't really see the sad bottom paint when we're on the water. Is there something awful that can happen from not being super diligent about bottom paint in fresh water? I get that in super warm climates or especially the ocean you can get some nasty growth/barnacles, but this isn't our lake. Is bottom paint in my kind of lake necessary for some reason other than as a biocide?
