Mercury Zeus POD Drive Trim Tab Single - Aluminum -



It is our recommendation that you replace both trim tab plates at the same time. This item is sold separately here, but should be be purchased as a pair or you can purchase the Zeus POD Drive Anode Kit which comes with 2 plates and the hardware included.

Zeus POD anodes found on fine yachts such as: Sea Ray, Mikelson. Marquis, etc. The larger version of these yachts will also use this additional anode.

  So what are Zeus POD drives, exactly? They're a relatively new power system that eliminates the need for shafts, struts, and rudders. Instead of using traditional running gear to transfer the engine's power into thrust.  A "pod," consisting of the transmission, outdrive, and propeller(s), is mounted right through the hull.
