[k6fee via Personal_Submersibles]

Be sure to use marine grade aluminum or it will dissolve like a zinc anode.
Marine aluminium doesn't corrode in salt water.

Hi All,  Happy New Year !              Can anyone tell me why I can't make all of my different thru hulls out of aluminum ?   Fittings that will be potted and so forth for electrical .
Thanks,
Brian
