For sheer unbridled power, speed and performance, Yamaha’s VF250 Vmax SHO (Super High Output) four-stroke outboards deliver where no other four-stroke or two-stroke can. This race bred outboard has been purposely designed to meet the competitive needs of bass boat fishing, skiing, racing and other adrenalin packed boating activities. The 4.2 litre, 24-valve, double overhead cam engine is not only extremely compact, but is lighter than another equivalent four-stroke on the market. The secret to its performance is the plasma-fused sleeveless cylinders which significantly reduce the overall weight while increasing the engine capacity. If speed is your thing, then there is no better option.

VMAX SHO’s have been engineered specifically to deliver unrivalled hole-shot and acceleration, with an equally impressive top-end speed. Our new V6 VMAX SHO ® outboards not only look great with their aggressive styling upgrades, redesigned cowling and eye-catching raised graphics, these high-performance engines also incorporate some great new features including Yamaha’s TotalTilt™ trim system, as seen on our new V6 Offshore range.  We have also increased the alternator output by a massive 40%, now producing 70 gross charging amps, enough to power an extensive range of electronic devices.

Features

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 Gauge

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.  

704 Premium Single Binnacle Control

This highly-polished, stylish looking, top mounted control allows for effortless one-handed control. The ergonomic design features a thumb operated trim and tilt switch built into the handle, as well as shift and throttle control functions, for convenient and comfortable operation. 

6x3 Concealed Side-Mounted Control

With its stylish chrome finish and ergonomic design, this mechanical control not only looks good, but provides effortless one-hand operation. The trim and tilt switch is comfortably located on the handle and features easily accessible neutral warm-up controls and externally adjustable throttle friction.

Genuine Yamaha Propellers

Prop choice makes a huge difference to outboard acceleration, top-end speed, handling and fuel efficiency. That is why Yamaha continues to push the technological boundaries in the design and development of our leading range of high performance props - ensuring every Yamaha outboard performs at its peak.   

VMAX Ventless Prop

These high-quality stainless steel propellers have been designed to harness the awesome power of Yamaha’s Super High Output (SHO) 4.2 Litre outboards, delivering superior acceleration, high-end speed and overall performance for bass, competition, ski and other high performance boats. 

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.

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.

Super High Output Design

The new V6 VMAX SHO ® outboards feature bold and aggressive styling upgrades, a redesigned cowling and eye-catching raised graphics, ensuring they look as impressive as they perform.

Battery Isolator (output)

The VMAX SHO V6 has the option of connecting an optional isolator lead to better charge house or trolling batteries.

High Output Alternator

The alternator output for the new VMAX SHO V6 has been increased by 40% on previous models, now producing 70 charging amps. This is handy for today's boaters wishing to use an extensive range of electronic devices.

VMAX TotalTilt™

Yamaha’s exclusive TotalTilt™ function allows for the complete tilt up or down of the outboard from any position with a simple double push of the Up or Down trim/tilt buttons. The new bracket allows the engine to tilt higher out of the water, helping to lessen the potential for corrosion, while the built-in tilt limiter automatically stops the engine tilt at a predetermined set point. 

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.

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.

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.  

Conventional - 6Y5 Round Gauge

Yamaha’s most affordable Tachometer and Speedometer gauges offer RPM, Trim Angle, Oil Pressure, Overheat Warning, Trip Hours, Total Operating Hours, Speed, Trip Distance, Time, Fuel Level, Low-Fuel Warning and Battery Voltage/Warning.

Direct Ignition

The direct ignition system, with plug cap and ignition coil, provides higher reliability and increased performance.
