Aluminium Shaft Anodes
- 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 anode.
- Aluminum 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.
- Size: 2 1/4"
