Features & Rigging Componentry
Yamaha's legendary three-cylinder two-stroke outboards are powerful, lightweight and compact. Excellent response throughout low and mid range RPM is achieved through superior exhaust manifold design and an ideal crankshaft arrangement.
3 Year Warranty
All Yamaha two-stroke engines come with a three-year warranty for added peace of mind.
Yamaha's unique marine alloy, YDC-30, has been developed exclusively by Yamaha to handle the harshest marine environments and is the result of years of Yamaha research and testing. YDC-30 delivers superior anti-corrosion properties that Yamaha outboards are legendary for.
Loop-charged scavenging creates a circular fuel flow for efficient transfer of exhaust gas and even distribution of the air-fuel mixture. The result is greater combustion efficiency for excellent performance and better fuel economy.
Maintenance Free CDI Ignition
The capacitor discharged ignition system provides strong spark and precise timing, preventing plug fouling, improving starting performance and reducing maintenance.
Power Tilt and Trim
Wide range power tilt and trim allows convenient engine operation and adjustments to the boat attitude to meet changing conditions while underway. Years of research and development have made Yamaha's power trim and tilt units reliable and extremely durable.
Precision Blend Oil Injection
Yamaha's exclusive Precision Blend multi point oil injection system injects the precise amount of oil needed by the motor to the intake manifold during engine operation. This feature eliminates the need to pre-mix fuel and oil. This system ensures quick response to the engine’s oil demands for reliability while minimising smoke and oil consumption.
Yamaha uses strategically placed aluminium and zinc anodes for maximum corrosion protection. These anodes are even larger than necessary, ensuring total effectiveness.

704 Premium Single Binnacle Control
This highly-polished, stylish looking, top mounted control allows for effortless one-handed control. The ergonomic design features a thumb operated trim and tilt switch built into the handle, as well as shift and throttle control functions, for convenient and comfortable operation.
Digital Round Gauges
Yamaha’s conventional digital multi-function gauges provide the real-time data required to maximise outboard performance and fuel efficiency. The two and three gauge illuminated display options provide rpm, trim, oil, speed, distance, time, overheating, battery, fuel economy/flow/consumption stats.
Genuine Yamaha Propellers
Prop choice makes a huge difference to outboard acceleration, top-end speed, handling and fuel efficiency. That is why Yamaha continues to push the technological boundaries in the design and development of our leading range of high performance props - ensuring every Yamaha outboard performs at its peak.
Yamaha Shift Dampener System
Many of Yamaha's mid-range and high horsepower props come with Yamaha’s exclusive Shift Dampener System (SDS). This system absorbs forces created when an engine shifts in and out of gear, resulting in a quieter, smoother and ‘clunk free’ shifting.
Alloy White K Series
These props deliver Yamaha's high-quality design and performance in a low-cost, lightweight propeller. They offer a good all-round choice for Yamaha outboards, coming in a wide range of sizes and pitches to suit every power requirement.
Alloy GP K Series
The newly released aluminium GP introduces a renewed blade geometry and Yamaha’s Shift Dampener System (SDS) for ‘clunk free’ shifting to the K series of props. Suited to lighter hulls, this exceptional prop delivers improved acceleration, speed, fuel economy and anti-ventilation.
Multifunction Tiller Handle
With the latest technologies, ergonomic design and features, Yamaha's optional Multi-Function Tiller Handle delivers effortless control, maneuverability and comfort.
