Hi,

I have a197? 43' aluminum hull houseboat on a freshwater lake near Atlanta, GA. AFAIK it has never been out of the water. It's located in a fairly large marina. I've been told that steel hull boats should have a sacrificial anode applied to help keep the hull from breaking down, but recently someone said that aluminum boats should have one also. Is that true, and if so can anyone tell me just how to do it or suggest a page or video that explains to how to apply one to aluminum hull boats in fresh water?

Thank you for any help!

Is your boat an inboard, or I/O, at 43 feet I'm guessing not an outboard. At any rate I'm guessing your boat has or had them.
If you have an I/O the anodes are generally located on the leading edge of the drive just above the anti-ventilation plate, , some people call it the cavitation plate.

I have 1997 20 foot aluminum Lund I/O, it has sacrificial anodes on the trim cylinders and on the transom shield.
