25HP

Yamaha 25HP 2 Stroke Outboard Engines are a reliable and efficient choice for boaters. With their lightweight design and powerful performance, these engines are perfect for a variety of water activities. Trust in Yamaha's reputation for quality and durability when choosing your next outboard engine.

496cc Two-Cylinder

Trusted two-cylinder two-stroke design is durable, powerful and extremely reliable.

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.

Anti Corrosion

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.

Ergonomic Carry Points

Ergonomically placed carry points located near the motor’s centre of gravity allow easy carrying and mounting.

Loop Charging

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.

Self-Sacrificing Anodes

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.
