Zinc anodes for the A30 prop shaft


Camp zinc and prop nut. The zinc is internally threaded and screws onto the prop nut, which has a thread to receive it. You may have to cut off the tip of the zinc to clear the rudder. I also cut down the nut, itself, to reduce the amount of zinc that had to be removed for clearance.

ElectroGuard prop nut and zinc is held on with a cap screw. Unfortunately, replacement zincs do not come with a new cap screw, so you need to order that separately. Bronze cap screws can be hard to locate.

Another kind of propnut and zinc. I don't know what manufacturer this is.

Standard "donut" zinc to fit around the shaft, if you have enough space. This would go between the prop and the stuffing box.
