2019 Malibu Boats, LLC Owner’s Manual • Page 176Do not wax powder-coated surfaces as the wax will collect in thetextured surface and be extremely hard to remove.If the boat owner begins to notice rust or deterioration of metalcomponents below the water, even when operated regularly infresh water, this should be brought to the attention of the authorizedMalibu dealer. In some instances, it is necessary to attach self-sacrificing zinc anodes, even when operated in fresh water. Besafe, rather than sorry!Salt Water Series Careand MaintenanceWhen boating in brackish or salt water, the post-outing cleaningis highly critical for the protection of the finishes. The potential forcorrosion means that boats operating in this type of conditionmust be equipped with self-sacrificing zinc anodes. Theseanodes are attached in several locations, including the transom,driveshaft and rudder. (Check with your authorized Malibu dealerto be certain that you are aware of all locations of these anodesas they will require periodic replacement.) The anodes serve tosignificantly reduce the potential for corrosive damage to thepermanent metal components on the boat.Malibu boats are equipped with a closed cooling system, (seethe Engine section of this owner’s manual), which reduces theamount of water utilized from the body of water during operation.However, SOME water is necessary and must be drawn on-boardand circulated. This function exposes interior portions of the boat,particularly some engine components, to operational exposure to saltor brackish water. The explanation of how properly flush the enginefollowing an outing appears later in this section.Failure to follow ANYof the Salt Water Seriesinstructions for care andmaintenance will void the warranty.
