Suzuki develops corrosion-resistant technology for boat engine parts

Japanese automaker Suzuki has developed corrosion-resistant technology for parts of boat engines to protect them from the impact of sea water.

The company announced this in a press release on 26 February, indicating that the corrosion-resistant anodizing treatment will reduce CO2 emissions by roughly 50% compared to other treatments.

The technology is also designed to withstand high temperatures and help outboard engine components last longer.

Contributing to Carbon neutrality

One of the main focuses of Suzuki is carbon neutrality, and the new treatment for outboard motor engine components contributes to attaining that goal.

With about 50% reduction in CO₂ emission compared to other such treatments, the technology significantly drives the world closer towards carbon neutrality.

The treatment can also withstand high temperatures to the engine components, including the cylinder block, cylinder head, and crankcase. 

“Outboard motors pump up large amounts of water such as seawater to cool the engine. This makes corrosion prevention treatments for the cooling water passages vital. The technology developed by Suzuki improves corrosion resistance against seawater by the uniformly applied anodizing treatment to the engine components that come in contact with the cooling water.”

According to the company, the treatment has been adopted to some specifications of the DF140B from August 2024, a first for mass-production models, and will progressively be adopted to other models’ specifications as well.

Increasing relevance

Suzuki has developed new technologies that have found application both in the automotive and other industries. 

Earlier this year, the company joined forces with Toyota and Daihatsu to build Mini-commercial battery electric vehicles (BEVs). 

The vehicles, though will bear the names of the different companies, will be based on their combined expertise. 

Last year, Suzuki also entered an agreement to build electric SUVs for Toyota, an indication of high achievement in EV technology since Toyota is a leading automaker with global recognition.
