What are Outboards

An outboard motor is the propelling unit of a boat and is made up of components that include an engine, gears, shafts and propellers. In some instances, the outboard itself fulfils a steering role. In addition to not needing onboard space for the engine and drive shaft as do inboard motors or stern drive motors (inboard-outboards), there are no worries over propeller shaft problems that arise from hull distortion.

Yamaha outboards are popular in waters around the world. In meeting each region's specific needs, Yamaha has achieved a lineup that boasts over 1,000 outboard spec variations. Specifications are refined according to every kind of application and boat type, naturally starting with horsepower but also encompassing transom length, fuel type and choices between manual or remote control handling and manual or electric starter.
