2017 Models: All except ProStar, as part of the Salt Water Package option.

If the boat is operated in salt, polluted or brackish waters, even temporarily, the boat should be equipped with a transom-mounted zinc anode to prevent damage to those metal parts coming in contact with the water.

The zinc is, by design, self-sacrificing. It is slowly eroded away by electrolytic action and requires periodic inspection for deterioration. When the zinc has eroded to approximately one-half (1/2) of its original size, it must be replaced to continue protection, or damage to other metal parts may result. 


The anode is mounted on the transom. 


There is no operation required. Boat owners should periodically examine the anode to determine how much erosion has occurred and consult an authorized MasterCraft Dealer to determine the appropriate time to replace it.
