Martyr Anodes
Martyr makes sacrificial anodes, the cheap metal that corrodes so your outboard, sterndrive or hull hardware does not. The range covers aluminum, zinc and magnesium in single anodes and engine-specific kits.
Choosing the alloy is simple once you know the water: magnesium for fresh, aluminum for brackish and most modern use, zinc for salt. Replace them when they are half gone, not when they are gone. Tell us your engine and where you boat and we will pick the kit.
Frequently asked questions
Which anode material should I use, zinc, aluminum or magnesium? Salt water takes zinc, fresh water takes magnesium, and aluminum is the general purpose choice that suits brackish and most modern use.
When should anodes be replaced? Replace them once they are about half consumed. Waiting until they are gone means the next thing corroding is your engine or hull hardware.
Do you offer free shipping in Canada? Yes, on orders over $279.99.
