Re: anodes on alum

1 annode should be enough. will you be storing in the water? on a lift? trailer? I personally wouldn't keep a boat in salt. I replace my annodes when they start to get thin.

Re: anodes on alum

I only have the engine mounted annode or sacrificial zinc on both my boats. I run them 2-3x a week in nothing but salt water, they are trailer and lift kept and I have no issues. If you keep trailered you should not have to replace the one you have for quite a while.
