GENERALCooling System Anodesp üFOR ALL 4 CYL. MARINE ENGINES12» «FOR ALL 6 CYL. MARINE ENGINESThere are 4 sacrificial zinc anodes in the raw water cooling systemnormally, although if an exhaust high riser is used there is one extrafit in it. Which are installed as per ill. 26 and 27.Remove and inspect anodes for galvanic erosion according to themaintenance schedule.Replace anode when material loss is 50 – 75 %.265 (option)3406017Anti-Corrosion AnodesIf additional electronic equipment is installed, each should havean individual anode or grounding device and all grounding devicesmust be interconnected. Follow recommandations of manufacturersof equipment.2706018NOTE:Inspect anodes every 30 days, or morefrequently if used in extremely salty water.Anode is to be replaced according to themaintenance schedule.21Boats that connect to an AC power source (shore power) requireprotection against increased potential of galvanic and “spray current”corrosion. For protection, a galvanic isolator can be installedin series with the grounding (green) wire in the shore power cablebetween the boat and the shore power outlet on the dock. The isolatorblocks direct current (DC) flow, but permits the passage of alternatingcurrent (AC) thus providing a path for ground fault currents.NOTE:If a boat is connected to an AC power source(shore power), and it is not equipped witha galvanic isolator, the zinc anti-corrosionanodes may be unable to handle the addedcorrosion potential.2843060215290602293
