The efficiency of an aluminum anode is high

✔ MerCruiser anodes meet or exceed mil-spec MIL-DTL-18001L - Zn which provides long lasting protection for those who have their boats in salt water

Specifically: Mariner 10-50 HP Yamaha 20-50 HP

Zinc anodes can be used in brackish water if the resistivity is not too high (approx
