Why Aluminum Over Zinc Anodes:
– Aluminum anodes offer many benefits over zinc anodes. To begin with, they have a higher driving voltage and thus higher corrosion protection capacity and last longer than zinc anodes. They are also less toxic, which gives less environmental impact. In addition, aluminum anodes are a better choice also for brackish water.
– Aluminum anodes provide up to 30% higher corrosion protection capacity and last up to 20-40% longer than zinc anodes of comparable size in salt water.

Will Volvo Penta continue to provide zinc anodes when aluminum anodes are a better choice for both salt and brackish water?
– We will gradually phase out and replace most of our zinc anodes with aluminum anodes for Aquamatic Sterndrives, S-drives and propellers as of Sep 1st 2021.

Can you mix aluminum and zinc anodes on the same drive?
– Aluminum and zinc anodes are compatible from a technical standpoint and may be mixed on the same drive.
– It will result in a more uneven anode consumption rate, where the zinc anode being consumed more slowly and the aluminum anode faster than normal. Although the total consumption is unchanged.
– Mixing zinc and aluminum anodes on the same drive will lead to higher protection capacity compared to if you use only zinc anodes. If you use only aluminum anodes the protection capacity increases even further.
– NOTE! Boats with aluminum hull or extra equipment protected by additional zinc anodes, we strongly recommend that those anodes are changed to aluminum anodes to avoid extremely high consumption rate of the aluminum anode on the drive.

Can aluminum anodes be used for all types of hull materials?
– Yes, no difference compared to using zinc anodes.
