Abstract
Abstract A marine drive is provided with a large volume anode, about 30 cubic inches, for galvanic protection. The anode (230) is a brick-like block member tapered along each of its height, width and length dimensions. The drive housing has an anode-mounting section (232) extending rearwardly therefrom and has a downwardly opening cavity (234) of substantially the same shape and volume as the anode, and receiving the anode in nested flush relation.
