VF250 VMAX SHO
Fast + Light + Fuel Efficient
With class-leading 4.2 litres of displacement and game-changing Super High Output four-stroke outboard technology, Yamaha’s new VMAX SHO has absolutely unbelievable hole shot and acceleration with equally-impressive top speed. Use of plasma fused sleeves and the latest composite materials have made these engines super light weight. In fact no production V6 outboard of equivalent horsepower four stroke on two stroke is lighter. It provides astounding power and performance, complete with Yamaha’s signature four stroke smoothness, convenience, and reliability. The Yamaha VMAX SHO represents the absolute leading edge in high-performance outboard technology, purpose-designed and built as the ideal power for bass boats and also a great option for social water ski and wakeboard 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.
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.
