Default Bennett Trim Tab Anodes

The anode on the underside of the port trim tab is spent. Are these anodes replaceable? The tabs are the classic hydraulic type measuring 12" x 11-1/2". Thanks!

A lot of us only have the Allen bolt head on the underside of the tab and the threaded 1/2 of a 3 " pancake zinc anode on top side of the tab. ( Less drag and flow disruption, and still good anodic protection when boat is not on plane.)

Pancake anodes are commonly available at most marine supply stores, locally and online and there are several anode specialty sites online .

General rule of thumb is to replace any sacrificial anodes which appear to be 1/2 gone , as the rest is very porous and will go much faster. In some cases a deteriorated anode can loosen and cause a very annoying vibration noise , or fall off.

Thanks. After a closer look I see these are Camp R2 zincs. Should be a simple replacement as long as that allen screw hasn't become galvanically welded.

It will come off easily. Loosen slightly with an A.wrench and spin the top 1/2 off.

Usually on that size Tab we use 1/2 of an R-3 on the top only of each Tab.
