The Yamaha F250 delivers the latest technology with unrivalled big power performance, ensuring you have the muscle and smarts to handle the most extreme offshore environments. This new generational 4.2 litre, big bore V6 offshore outboard has the largest capacity in its class while weighing in at just 253kgs. This unbelievable power-to-weight ratio is achieved through the use of an innovative plasma-fused sleeveless cylinder design, which greatly reduces the overall cylinder weight while achieving increased engine capacity. The innovations don’t just stop there. This exceptional outboard includes all of Yamaha’s latest technologies including an electronically controlled throttle valve, variable camshaft timing and digital electronic controls.

Features
Digital Boat Control System
Helm Master® EX is an industry-first fully integrated digital boat control system that delivers next level control over your boat for increased boating and fishing enjoyment. Now available for single and multiple outboard engine applications.
4,200cc V6 Engine
Featuring plasma-fused, sleeveless cylinders, double overhead camshafts (DOHC) and four valves per cylinder, these 4.2 Litre advanced V6 engines are extremely light, powerful and fuel efficient.
Digital Electronic Throttle
The 'drive-by-wire' throttle and shift offers the driver simple, smooth and precise operation, for a more enjoyable riding experience.
Plasma Fused Cylinders
The plasma fusion process creates a cylinder wall surface that is 60% harder than steel, removing the need for conventional steel cylinder sleeves. The removal of these sleeves significantly reduces weight while increasing capacity in the engine, resulting in an improved power-to-weight performance.
Compact In-Bank Exhaust System
Yamaha's ongoing weight-saving program has delivered an innovative in-bank exhaust system, with the manifold integrated into the cylinder head. Along with other weight-saving technologies and materials, helps to create a supremely compact and light engine design.
Electronic Throttle Valve
The electronic throttle valve provides sure and more precise valve opening and closing according to each engine temperature and atmospheric condition. This system works in tune with the fuel injection and ignition systems, to deliver incredible response and exceptional fuel economy.
One-Touch Start-Stop for Multiple Engines
This optional system for twin and triple installations automatically synchronises engines to allow a simple one-touch start and stop capability, for ease of use.
Variable Trolling Control
Yamaha’s variable trolling control allows the skipper to precisely adjust the engine’s idling speed from 600 to 1000 RPM in 50 RPM increments. The ability to finely tune the trolling speed allows fisherman to perfect their lure presentation when chasing different species of fish.
Shift Dampener System (Prop)
Yamaha’s Shift Dampener System (SDS) propellers greatly reduce the noise associated with shifting an engine in and out of gear by absorbing the forces generated when forward and reverse gears are engaged.
Variable Camshaft Timing
The Variable Camshaft Timing (VCT) advances and retards the camshaft timing according to the engine RPMs. This in combination with the electronically controlled single throttle valve system and long intake manifold boosts low and mid-range torque for optimum acceleration.
Rigging Componentry
Digital Boat Control System
Helm Master® EX is an industry-first fully integrated digital boat control system that delivers next level control over your boat for increased boating and fishing enjoyment. Now available for single and multiple outboard engine applications.
Remote Control Security System
Yamaha's optional Customer Outboard Protection (Y-COP) engine immobiliser system is easy to use and highly effective in stopping unauthorised start-ups when your boat is unattended. Simply push the button on the neat and simple remote to lock and unlock the engine.
Command Link - 6Y8 Round Gauges
Using Local Area Network (LAN) technology, these digital round gauges provide accurate and real-time tachometer, speed and fuel management stats, including fuel flow/consumption/economy (up to two tanks), trim level, battery voltage, push button trolling speed adjustments and more.
Command Link - 6YC High Definition Gauge
This high definition, colour display uses Local Area Network (LAN) technology to deliver accurate and real-time stats for single and twin engine setups. The customisable day/night gauge delivers information on fuel flow/ economy/ consumption, trim level, battery charge, speed, push button trolling and more.
Command Link Plus - 6Y9 High Definition Gauge
This high resolution, five inch, fully customisable LCD display can monitor up to three Digital Electronic Controlled (DEC) outboards. Data includes trip distance, water depth and temperature, shift position, fuel flow/ consumption/ economy, rpm, trim level, oil pressure, engine temp, battery charge and more.
Command Link Plus - CL7 Premium Touchscreen Gauge
Our latest and most advanced display has been developed for Yamaha's range of Digital Electronic Control (DEC) outboards. The user-friendly, seven-inch touchscreen is fully customisable and can monitor up to four outboards. Functions include GPS navigation and the ability to connect to a fish finder, sonar, radar and camera.
