Alpha 1ALUMINIUM ANODE DRIVE KIT Mercruiser

All in one box kit for Alpha 2 Stern Drives.Kit 

Performance Metals Aluminium Anodes feature patent pending 'Wear Indicator' which tell the  boater when it's time to change. This plastic indicator is embedded in the anode and appears in the surface of the anode when it appears.
- Aluminium/Indium alloy is more active so it gives better protection.

Advantages of Aluminium Anodes

Voltage:            Aluminium anodes generate a lower voltage (-1.1V) than Zinc (-1.03V) providing increased protection.Longer Life:       Aluminium anodes will last between 30% and 50% longer than zinc. The Ampere Hour Capacity (AHC) per pound-weight of aluminium alloy is 1150 AHC compared to 368 for zinc.

Lighter:             Aluminium alloy is two and a half times lighter than zinc.

Eco-Friendly:     Aluminium alloy does not pollute.

Red Spot:          Patented Red Spot wear indicator appears when 50% of the anode is wasted

Re-Immersion:   Aluminium alloy works immediately on re-immersion because the aluminium hydroxide is porous. Zinc hydroxide is impermeable and must be burnished off before the zinc anode is effective.

Waters:             Aluminium alloy is equally effective in fresh, brackish and salt water.

Boat:                Aluminium anodes can be used on any type of hull material â€" fibre glass, aluminium or steel, without fear of overprotecting.

- 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.

Alloy meets meets military specification MIL-A-24779 (SH).
