This plastic indicator is embedded in the anode and appears in the surface of the anode when it wears. Aluminium/Indium alloy is more active so it gives better protection Essential for Mercury sterndrives - Zinc will not provide the correct protection Recommended for both salt and freshwater on Mercury sterndrives Last up to 50% longer than zinc anodes Aluminium anodes "self-clean" in freshwater - Zinc anodes form a coating that stops them working within a few months Environmentally friendly Mounting hardware included Attractively packaged with clear information to aid with selection and installation - reducing the need for trained store staff Alloy meets military specification MIL-A-24779 (SH) Mercury # 826134Q & Honda # 41109-ZW1-003
