Introducing the Yamaha F25GETL
 
Technology the world trusts Whether you enjoy the thrill of water sports or just relaxing on your boat, choose the engine that helps you get more out of your time on the water. Every engine in our range uses Yamaha's latest marine technologies, engine layouts and ingenious intake and exhaust systems - and our 4-stroke development has been so successful because, rather than just adapting ordinary automotive engines for the water, we design and build our marine-speci cation 4-strokes from scratch. The 25hp is available with electric or manual starting, remote or tiller steering, short or long shaft and Power Trim & Tilt.
 
Unique power-to-weight performance This new-generation twin cylinder, 4-valve engine is around 25% lighter, delivering unprecedented power for such a portable unit. Easy starting and smooth running are assured by the battery-less EFI system and a choice of electric, manual or electric/manual starting options are available
 
Latest, one-piece top cowling design Instantly recognisable as a brand new Yamaha, this smart engine features our latest one-piece cowling, with stylish graphics and a solid feel that any owner will appreciate. A cleverly designed water-draining air intake duct is built into the cowling too
 
Easy starting, security - and VTS Starting - even from cold or after storage really is as easy as starting a car. Exclusive to Yamaha, the combination of our legendary PrimeStart™ and new battery less EFI systems ensures that your engine res up rst time, every time. What's more, you can choose VTS (Variable Trolling Speed) and Y-Cop immobiliser security options too.
 
Now compatible with Yamaha's Digital Network Gauges You'll nd the new 25hp very easy to handle and comfortable to drive, thanks to its many new features. Remote control models for example, are fully compatible with our advanced Digital Network system, which o ers the driver a comprehensive selection of information, as well as a more precise and relaxing level of control.
 
High-output alternator - keeps the power coming The 25hp will be put to a wide variety of tasks, from shing at night to coastal cruising, so its High-output alternator is a comforting feature, ensuring that power should always be available to start the engine – even after prolonged periods of idling or if you've been running at low revs and using numerous accessories
