Power & Performance

Convenience & Control

Charging Power
Alternator
- The convenient option of a voltage regulator/rectifier providing a reliable 12V 6A power supply for charging batteries and running lights.
- Great for a bit of exploring or fishing at night!
Improved Response
Prime Start
- Exclusive to Yamaha, PrimeStart™ makes starting as easy as starting a car.
- Automatically controls the ‘warming up’ process.
- Eliminates the need for a choke or revving in neutral for cold starts.
Seamless Performance
Smooth Operation
- With impressive features like a long span mounting and labyrinth exhaust system, this engine delivers smooth and quiet power.
Compact Power
Twin Cylinder SOHC Engine
- Small in size, but big in performance, the 212cc, 9.9HP, twin cylinder, single overhead camshaft (SOHC), four-stroke engine is lightweight and portable.
- Ideal for tinnies, inflatables and poly boats.
More Thrust
Dual Thrust Propeller
- The big-diameter, low-pitched, dual thrust propeller delivers instant power by redirecting exhaust gases away from the propeller.
- This reduces reverse ventilation and generates more power to the water to push bigger loads in both directions.

Increased Grunt
Higher Gear Ratio
• The higher gear ratio of 2.92:1 can operate a large diameter propeller, allowing the outboard to push greater volumes of water, for improved thrust and better performance.
• The gears are specially hardened to withstand the toughest working conditions – for long-term durability.
Easy Flushing
Fresh Water Flushing Device
- Simply connect a garden hose to the outboard's input port to flush out salt and debris without starting the engine.
- This helps prevent corrosion, extends the life of the outboard and keeps things nice and quiet for your neighbours.
More Convenience
Power Tilt
- Power Trim (PT) allows for the quick and easy tilting up and down of the engine and fine trim adjustment, for a more enjoyable boating experience.
