Nautical Anodes 
Why Boat Anodes are necessaryAnodes can simply be described as small guards that protect a boat's engine from deterioration. Anodes are crucial to the health of an engine as they protect underwater metals from galvanic corrosion. Anodes get worn away as a first line of defence to prevent other outboard engine parts getting destroyed. This is why you will often hear them referred to as “sacrificial anodes” or “sacrificial metal”. They will give off electrons to be depleted before any other metals in the engine are targeted. The anode will eventually have so little left that it will no longer be useful and therefore must be replaced. It is recommended that you should replace anodes as and when they are half eroded or dissolved. This is generally once a year. Failure to replace these anodes could in turn lead to an extremely expensive repair bill. Zinc anodes have been recommended as best choice for salt water for decades – What has changed?The early aluminium anode alloys were alloyed in a way that made them less effective than zinc anodes and passivated more easily in many waters and some of them also contained mercury, which is harmful for the environment. Alloying has developed over the years and the aluminium anodes offered today are more effective than zinc anodes and as a consequence the supply of Zinc anodes is being phased out by most manufacturers. We supply an extensive range of boat anodes at competitive prices; zinc and aluminium for saltwater use and magnesium for freshwater. Should you require an anode which is NOT shown, please contact us. Available for purchase in our store you'll find common boat anodes for a range of fitment locations, including hull and prop shaft. Please choose your desired type below, if you need help identifying the correct part for your boat, please call us on +44(0)1923 276000 and we'll be happy to help. Note: Anodes for Sterndrives can be found by selecting the engine manufacturer, e.g. Volvo Penta. |
