For 77Z to consider, with his new Crestliner 'tin' boat ...
Anode Install: They say a picture is worth a 1,000 words, so I’ll be brief. Quite simply I don’t paint or I remove the paint where I’ll affix a common ‘rudder’ zinc to a tin hull. For an anode to work correctly, it must be in full contact with bare, clean metal. I drilled out, then wet out the wood transom core with thin epoxy, then imbedded a SS threaded-insert deep into the wood using thickened epoxy once the thin stuff had ‘kicked’ (tacky, i.e., starting to cure). This makes sure that the 2 epoxies chemically bond with each other, making a stronger junction, and albeit a waterproof one to boot!
Add goop of choice (5200, etc.) to fill up the void. Once goop cured, drill for a tap drill size. Then I just affix the rudder 'zinc' anode (NOTE I use aluminum anodes on saltwater tin OB-powered boats!) affixed by a short SS bolt, gooped up well (bolt threads only) with marine synthetic water-resistant grease, e.g., OMC/Bombardier ‘Triple Guard’ grease. FYI, that chart and info fromwww.boatzincs.com is a great resource!
Simple and it works
