Proven design, unmatched versatility, unbeatable value with an outstanding power to weight ratio plus world renowned reliability. There's plenty of reasons to consider Yamaha's 50H for your next boat. The proven three cylinder design with loop charged fuel intake delivers smooth, responsive and efficient power. Yamaha's precision blend oil injection (optional) ensure optimum smooth running an power delivery.
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.
100 to 1 Fuel Oil Ratio
Superior manufacturing techniques allow a leaner oil mixture, reducing smoke, odour and engine carbon build-ups, while also reducing oil consumption and running costs.
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 to handle the harshest of 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.
Shallow Water Drive
The shallow water drive system allows the engine to be quickly set and operated at a tilted angle allowing safe navigation through shallow water.
703 Side-Mounted Control
One of Yamaha's best selling controls, this mechanical remote offers comfort, simplicity and flexibility. With its new ergonomic grip, reversible right-hand or left-hand installation, and convenient trim and tilt operation, this control offers all-round functionality and value.
6x3 Concealed Side-Mounted Control
With its stylish chrome finish and ergonomic design, this mechanical control not only looks good, but provides effortless one-hand operation. The trim and tilt switch is comfortably located on the handle and features easily accessible neutral warm-up controls and externally adjustable throttle friction.
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.
