Outboard engine anodes are sacrificial metal parts that are installed on the underwater portions of an outboard engine to protect the motor from corrosion. The anodes made of a more active metal, such as zinc, aluminum or magnesium, which will corrode before the more passive metal (e.g. steel or aluminium) of the motor. Outboard engine nodes will corrode away over time, protecting the motor from damage. We highly recommend you check and replace the anodes on a regular basis as part of the routine maintenance of an outboard motor.
As mentioned above, outboard engine anodes are made from three metals – aluminium, magnesium and zinc.
Aluminium outboard engine anodes offer protection in salt and fresh water, whilst zinc outboard engine anodes are more suited to salt water as the impact strength of the metal is superior compared to aluminium and magnesium. Magnesium outboard engine anodes are only suitable for use in fresh water, as the alloy reacts far more rapidly when exposed to sea water.
