4-Front Corrosion Protection

Honda’s 4-Front Corrosion Protection System fights off corrosion from harsh marine environments.  This patented double-sealed, multi-layer paint process uses 4 different layers to protect the engine.

• The base is a corrosion-resistant Honda aluminum alloy, followed by a double-sealed treatment.
• An epoxy primer undercoat is applied.
• An acrylic resin metallic coating is baked on.
• A clear overcoat of acrylic finishes the process.

Honda engines have several other features designed to help protect them from the harsh marine environment:

• Sacrificial anodes protect the engine from galvanic corrosion. 
• All fasteners and hardware are either stainless steel or a specially treated Dacro material. 
• All wiring connectors are sealed to prevent water intrusion.
• Fresh water flush ports on select models allow you to flush the engine with a garden hose.
