1. Fresh water boat docked in fresh water (Lake Erie) from May to October
How often should the anodes be changed. Every year. Pitted at this point but not too bad. See pic
2. I added a prop anode. Which is standard on bravo 3 after 2004 ish. If I buy bravo 3 prop anode set for 2004 and up are the other anodes the same at my 98. Basically is the 98 set the same at the 04 other than the 04 has a prop anode.
