50hp
Ideal for towing skiers or wakeboarders, the compact 50hp lets you have fun on the water, but with a clear conscience – why? Because it's the cleanest and most economical engine in its class.
 
Maximum enjoyment. Minimum emissions.
Yamaha's Electronic Fuel Injection system (EFI) ensures cleaner performance and super-efficient consumption of fuel, all in an engine that delivers impressive power, high speeds and serious torque in the mid-ranges.
The 50hp also includes a number of unique Yamaha features, each designed to provide a smooth, comfortable and enjoyable ride. Among them are the Wide Range Power Trim & Tilt system, giving you full, relaxed control – and PrimeStart™ ignition – as effortless as starting a car.
