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.
Features & Rigging Componentry
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.
The direct ignition system, with plug cap and ignition coil, provides higher reliability and increased performance.
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.
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.
Conventional - 6Y5 Round Gauge
Yamaha’s conventional digital multi-function gauges provide the real-time data required to maximise outboard performance and fuel efficiency. The two and three gauge illuminated display options provide rpm, trim, oil, speed, distance, time, overheating, battery, fuel economy/flow/consumption stats.
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.
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.
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.
