Honda produces all of its 4-stroke outboard engines at its Hosoe Plant in Shizuoka Prefecture, Japan, and supplies them to North America and Europe, the two main markets, as well as to other markets around the world. Ever since the introduction of the GB30 in 1964 (first model), Honda has pioneered the development and production of 4-stroke outboard engines with a low impact on the environment based on the philosophy of our founder that "Watercraft should not pollute the waters they ply." Our lineup consists of 19 models, from the 2 horsepower BF2 to the 225 horsepower BF225. They all incorporate a wide variety of technologies based on the concepts of being "environmentally and people friendly, economical and high-quality outboard engines."
Exhaust gas emission regulations for outboard engines are being strengthened in order to protect the global environment. Honda was one of the first companies to incorporate advanced technology in outboard engines, based on technology it developed for automobiles and motorcycles, such as the PGM-FI (Programmed Fuel Injection) system featuring advanced combustion control, VTEC (Variable Valve Timing and Life Electronic Control), lean burn control (high air-fuel combustion ratio) and Honda's unique BLAST (Boosted Low Speed Torque) outboard engine technology. Honda outboard engines have achieved an unparalleled level of customer satisfaction around the globe by providing high output and outstanding fuel efficiency. All Honda outboard engine models clear the most stringent exhaust gas emissions regulations, including the EPA (Environmental Protection Agency), CARB (California Air Resources Board) and EU RCD (European Union Recreational Craft Directive).
All outboard engines discharge exhaust gas into the water. Since 2-stroke engines burn a mixture of gasoline and oil, this means that oil is discharged into the water. The GB30 was developed at a time when all outboard engines were 2-stroke, and 4-stroke engines were not considered feasible because of the large handicap due to the power weight ratio. Honda was the first company to clear the Boden Lake regulations in 1993 (first exhaust gas regulations for outboard engines in the world), and received considerable attention as a result. Currently, over 60% of all outboard engines are 4-stroke type. The history of 4-stroke outboard engines is synonymous with the history of Honda outboard engines.
This feature consists of intelligent technology. The minimum amount of gasoline required is injected during normal operation to boost fuel economy, and optimum control of the fuel injection volume and injection timing is performed during acceleration to enable acceleration performance to be enhanced.

Honda outboard engines feature a smooth flowing form and silver color that reflects the surrounding environment to express the integration of people and nature. The techniques used to incorporate a 4-stroke engine in a compact package and design that combines functionality and beauty have received high acclaim overseas. A wedge shaped design has been adopted for the BF60 that features BLAST technology, projecting an image of the best-in-class acceleration.
