The bolt and nut arrangement was reversed from the original zinc installation, which would allow the primary zinc to be replaced without the need to remove the rudder. Two ZHC-2 zinc anodes ($32.56) were ordered and received.
As the pictures below depict: Wire ring terminals were attached to 10 AWG, green, marine rated, tinned wire ($40.00) and installed under two 3/8"-16 x 3-1/2" grade 316 stainless steel hex cap screws and on top of 1-inch diameter washers. On the exterior side, 1.5 inch fender washers with nylon lock stainless steel nuts were installed securing the bolt installation to the hull. The bolts were sealed with 3M 4200 adhesive sealant. Excess sealant was trimmed clean. The new zinc anode was installed with 1-inch washers and nylon lock stainless steel nuts. The 10 AWG green wires were routed and connected to both boomkin stay internal mount bracket bolts. The wood floor piece in aft-most bottom of the lazarette was rotted through and broke apart during the routing of the wires - it would need to be replaced. The cost of the hardware was $13.70.
