    Default Aluminum anode vs. zinc anode on O.D.

    Hello all,

    Changing the anodes on my DP-Sm O.D. and was planning on using Aluminum anodes, I run the boat in salt water. Will aluminum anodes be okay?

    Been using aluminum anodes for 2 seasons in saltwater...Work just fine. Remember to change ALL of your anodes on the boat to aluminum not just some. You should not mix zinc and aluminum.
