[quote BROWNBAGGN]I was reading your zinc anodes on the back of your boat near your motor, will get a film on it and needs to be cleaned regularly to ensure proper grounding of your boat in the water.[/quote][font "Comic Sans MS"][#800000][size 3]Me thinks you didn't read far enough. Zinc anodes (also called sacrificial anodes) are there to protect your outboards metal from corroding when used (primarily) in seawater. When two dissimilar metals are placed in seawater, one of them will corrode due to a process called galvanic corrosion. While it can, and probably does, occur in fresh water, it is negligible. My old 11 year old boat motor wore the same anode for 11 years with no visible signs of corrosion anywhere on the motor. I never cleaned it and there was just barely a discernible amount of corrosion visible on the anode. It wouldn't hurt to clean it, but certainly isn't required unless you intend to run it in the Great Salt Lake.[/size][/#800000][/font]
