    Ducky - don't put zinc anodes back in for fresh water - use magnesium or aluminum...come over and see me and I'll 'splain it to you!!

    Sorry I just used "Zinc" as a generic term. The "anode" purchased with the maintenance kit was the same part number in the manual.

    I tried drilling it with an easy out and the whole thing turned to mush, was able to break it all up and get it out, new one installed. Thanks everyone
