• Action: To Do List item A0070 – Replace Isotherm thru hull zinc.
• Completed:  3 April 2016
• Cost: $47.19

One Isotherm SP refrigeration system replacement zinc anode with mount screws was obtained at cost of $26.99.  Another replacement zinc anode without mount screws was obtained at a cost of $20.20 as a spare.  The additional cost of $6.79 for two very small mount screws is not a purchase option that will be repeated.

The Isotherm thru hull zinc was removed using a Allen hex key wrench.  The surface of the thru hull was sanded clean using a Dremel sander.  The new zinc anode with screws were installed to confirm fit, and then removed as the thru hull needed to be removed, resealed, and reinstalled.
