Mercury SeaPro Commercial Outboard Range
Mercury SeaPro commercial outboards are purpose-built and engineered for commercial use, designed to be ultra-reliable partners for those who make their living on the water. From 15hp to 500hp, SeaPro Outboards have earned their credentials for reliability by performing under the toughest working conditions possible to deliver trouble-free operation year after year.
MercFusion Paint System
Mercfusion is a proprietary paint process engineered to handle the extreme marine environment. It utilizes a multi-stage process including:
- EEP (Electro-Deposition Priming): Seats out the environment.
- Irridite (Metal prop & sealing): Provides a highly resistant barrier.
- Powder Paint (Top Coat): Thicker, harder, and tougher for enhanced durability.
This process results in a harder, thicker, and tougher finish than provided by any other brand.
Rigorous Testing = Legendary Durability
Mercury engines undergo extensive testing in extreme conditions, including vicious big strikes, saltwater spray booths, high humidity chambers, and hot and cold water temperatures. Each engine is run for thousands of hours to prove its undeniable durability. This meticulous testing is backed by leading corrosion protection and warranties.
Corrosion Resistance
Mercury SeaPro outboards feature a comprehensive suite of corrosion defenses, including superior metals, intelligently designed cowlings, sealed electricals, more stainless steel components, sacrificial anodes, and the multi-stage MercFusion Paint Process. This allows for an industry-leading 3-year corrosion warranty.
SeaPro Commercial Warranty
SeaPros are engineered for the long term, backed by a 3-year (2+1 year) SeaPro Warranty* for the Australia & New Zealand region. This ensures your investment is well protected, supported by a vast network of sales and service dealers.
