Corrosion Blocking Paint & Coatings
Mercury’s exclusive multistep process
Corrosion Blocking Paint & Coatings

Key components receive an electro-chemical treatment called “hardcoat anodizing.” This coating increases corrosion resistance, resists wear, and provides better adhesion for paint.

  • Protection starts with Mercury’s exclusive low-copper aluminum alloys.
  • Iridite sealing provides a corrosion-resistant barrier before paint is applied.
  • Electro Deposition Paint primer creates uniform coverage that seals out the environment.
  • The powder paint top coat is harder, thicker and tougher than conventional paint.

 

Corrosion Resistant Aluminum Alloys
Maximum anti-corrosion protection.
Corrosion Resistant Aluminum Alloys

Most competitors use alloys with 2% to 4% copper content which will corrode faster than our Mercalloy®, XK360 or A356 alloys.

Alloys are a combination of aluminum, copper, silicon, and other elements. When immersed in water, electrons begin to flow within the material. Aluminum is corroded by the presence of copper. Low copper content reduces the opportunity for that interaction resulting in better strength and corrosion resistance.

The Only 3-Year Corrosion Warranty
All Mercury outboards are backed
The Only 3-Year Corrosion Warranty

Mercury outboards are designed and built from the ground up to give you the most enjoyment for as long as possible on the water.

We do more than any other manufacturer to ensure corrosion won’t interfere with your fun.

Mercury’s corrosion warranty is supported by the strength and service expertise of one of the largest dealer networks in the country.

Unmatched Internal Protection
Mercury’s exclusive SS38 Salt Shield
Unmatched Internal Protection

Yellow indicates passageways treated with Mercury® Salt Shield coating.

  • Provides industry-leading corrosion resistance in water-cooling passages.
  • Flushed into the powerhead and water passages to protect the engine from the inside out.
2x More Stainless Steel

2x More Stainless Steel

Amount of stainless steel on a four-cylinder Verado® vs. competitive 150hp four-strokes.

Mercury outboards contain at least twice the amount of stainless steel as the competition. Hardened steel is friction welded to corrosion-fighting stainless steel, producing strong and reliable shafts. This ensures saltwater only comes in contact with stainless steel.
