Re: Zebra Mussels - Lakes
We've had the little buggers for decades here on Lake Michigan. I've had them take up residence in the intake on my Catalina 309, but never approaching the point where they might impede the flow of water to the heat exchanger. When I see that they're present, I just clear them out. Swabbing a little bottom paint in there couldn't hurt, but they have not really been a problem.
