NEVER MIX Zinc and Aluminum Anodes on the same vessel.
•Zinc Alloy Anodes = Salt water only
◦Not recommended for use in fresh water
◦Alloy is manufactured to meet or exceed US Military Specification (MIL-A-18001K)

•Aluminum Alloy Anodes = Salt or Brackish water
◦Not recommended for use in fresh water
◦Proven to last longer than zinc due to increased capacity
◦Alloy is manufactured to meet or exceed US Military Specification (MIL-A-24779(SH))

•Magnesium Alloy Anodes = Fresh water only
◦Not recommended for use in salt or brackish water
◦The only alloy proven to protect your boat in fresh water

You need to check to see what you have....
I'm a freshwater guy, the "old salts" on here came help you tons more on ocean use.

Not sure what type of anodes the previous owner had on it but I can say they had very little or no pitting. I recently changed all anodes over to aluminum because my boat sees brackish water often.
