Martyr Anodes CM984325Z Martyr 984325 Zinc Anode For Mercury Mercruiser

It was here the next day

Ordered prior to the most severe pandemic restrictions, so arrival was better than expected. First time using the automated "tower of distribution", and I swear that 4 seconds after I identified myself, out spat the package. As for the product, it is a molded piece of metal with no moving parts that attaches under the cavitation plate and clears the prop from behind. It does provide the proper attitude (when installed and positioned correctly), to offset steering torque so that it's not a struggle to keep the boat on course, especially at full throttle. It's like power steering with a tiller motor. Make your arm sore from fighting those big fish, not your outboard.
