FONP boat engine anodes are essential components for protecting marine engines from galvanic corrosion , a very common phenomenon in aquatic environments. These anodes, often called sacrificial anodes , deteriorate in place of the engine's metal parts, preserving their integrity and extending the life of the engine itself.
Why choose FONP anodes for boat engines?
-
High quality materials
FONP anodes are made with pure and certified materials to guarantee effective protection :
-
Zinc : Perfect for use in salt water .
-
Aluminum : Ideal for brackish (mixed) water .
-
Magnesium : Recommended for protection in freshwater .
-
Specific protection for marine engines
Designed to protect the most vulnerable parts of engines:
-
Outboard motors : Submerged parts such as the gearcase, propellers and covers.
-
Inboard engines : Heat exchangers, manifolds, rudders and shafts.
-
Cooling : Heat exchangers and water tubes.
-
Ease of installation and compatibility
FONP anodes are compatible with engines from all major manufacturers (Yamaha, Mercury, Honda, Suzuki, Volvo Penta, etc.) and are available in various shapes :
- Bar anodes
- Disc anodes
- Bolt anodes
- Specific anodes for engine foot
-
Long life and reliability
- Designed to wear gradually without compromising protection.
-
Rigorous quality controls ensure durability and consistent performance.
-
International certification
- Compliance with industry standards, such as MIL-A-18001K for zinc anodes and EN12496 for aluminum anodes.
Types of FONP anodes for boat engines
-
Zinc anodes
- Ideal for use in salt water .
- Mainly used in outboard motors and underwater components.
-
Aluminum anodes
- Perfect for brackish or mixed waters.
- Reduced weight and longer life than zinc in these environments.
-
Magnesium anodes
- Ideal for engines operating in fresh water .
- They offer maximum protection in low-conductive environments.
How do FONP engine anodes work?
- When the metals in the engine are exposed to water, an electrochemical reaction occurs.
- FONP anodes, being more reactive, corrode before the metal parts of the engine.
- This process protects the engine, minimizing damage caused by galvanic corrosion.
When to replace FONP anodes?
- Check the anodes regularly : they should be replaced when they are worn more than 50% .
- The frequency of replacement depends on the aquatic environment and the use of the vessel.
