Replaced Zinc, 4/8
Cape Dory 28' cruisers require only one sacrificial zinc anode to protect the underwater metals from corrosion. It's a "perry nut" type, on the end of the prop shaft. Last year's zinc was about 1/2 gone, so it needed to be replaced for the start of the season.
Our boat's shaft is 1 1/2" diameter, which takes a prop nut zinc size "F". I found it in a few places online, including Hamilton Marine and BoatZincs.com. The zinc is relatively inexpensive, at around $15. Generally, only the zinc needs replacing, not the entire bronze prop nut, which is much more costly at about $90.
