Yamaha Four Stroke 250HP Outboard Engine

Yamaha Four Stroke 250HP Outboard Engine
F250

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.

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.

Compact In-Bank Exhaust System

The electronic throttle valve provides sure and more precise valve opening and closing according to engine temperature and atmospheric conditions. 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.

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.

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.
