How should you choose your Yanmar anode: zinc, aluminium or magnesium?
The maintenance of your hull and shaft line depends on carefully selecting your equipment. DAM Marine helps you avoid frequent ordering mistakes. It is essential to understand the relationship between the type of water in which you navigate and the metal used for the protective part.
- The zinc anode is intended exclusively for use in salt water. It is the reference alloy for classic marine outings.
- The magnesium anode must be used only for fresh-water navigation. Its rapid dissolution rate would make it ineffective at sea.
- The aluminium anode is versatile and suitable for use in salt water as well as brackish water, such as in estuaries.
Compatibility with Yanmar engines and saildrives (GM, YM, JH series)
To reassure every buyer, we detail the Yanmar series covered by our catalogue. Our parts are perfectly suited to classic marine engines, especially the 1GM, 2GM and 3GM series, as well as Yanmar YSB references. Compatibility also extends to modern YM series engines, such as the 3YM20, and JH engines, such as the 4JH2.
For transmission systems, our models cover sail drive units from SD20 to SD60 generations.
It is crucial to know that each engine anode is installed on vital components. These sacrificial elements are positioned on the engine block, heat exchanger, shaft line or exhaust manifold to block electrolysis.
Complete your maintenance: Yanmar kits, gaskets and impellers
Replacing your Yanmar anode often requires changing the associated sealing gasket, especially copper models that deform when tightened. To guarantee sealing, plan for this essential step.
Yanmar maintenance kits and complete anode kits, sometimes in two parts, greatly simplify overall drive maintenance. It is also strongly recommended to check or replace the cooling impeller during this routine maintenance operation.
