Yamaha VF250 4.2L V6 V MAX SHO 20 in.

Convenience and Control

• CHARGING POWER: The V6 V MAX SHO now produces up to 70 gross amps of charging power. This exciting, 40 percent increase in charging is more than enough juice to power all your marine electronics. They can also be equipped with an optional isolator leading to better charging for house or trolling batteries.
• V MAX SHO® SERIES PROPELLERS: Designed exclusively for V6 V MAX SHO® 20-inch-shaft outboards, V MAX SHO Series propellers are available in one-inch pitch increments from 22 to 27 inches, for fine-tuning wide-open-throttle RPM for tournament-level performance.
• FAST, EASY TILTING: With a quick double-tap of the trim button, Yamaha’s exclusive, TotalTilt® performs a full tilt up or down, until it reaches the trim rams. This makes trailering quick and easy and is handy when a complete up or down tilt is needed.

Power and Performance

• HOLE SHOT & TOP SPEED: With a top speed that’s 1.85 mph faster and a lightning quick hole shot, this fast bassin’ machine is still tough to beat. In fact, it’s powered five of the last seven Bassmaster® Anglers of the Year.
• COMPACT & POWERFUL POWERHEAD: Plasma-fused sleeveless cylinders are lighter and 60 percent harder than steel. They also allow us to enlarge cylinder bores without increasing their dimensions--which creates 4.2 liters of big-bore displacement, without adding weight.
• RESPONSIVE THROTTLE: Midrange punch and instant throttle response created by Variable Camshaft Timing has to be felt to be believed.
• THOUGHTFUL ENGINEERING: Smart engineering throughout the V MAX SHO® saves weight, from the cowling to the engine bracket to the lower engine pan.
• SMART DESIGN: Yamaha's exlusive In-Bank Exhaust System exits downward through the center of the "V" rather than on the exterior side. This increases combustion efficiency, creating more power and torque, and also results in a more compact shape.
• OVERALL PERFORMANCE: This superior design--with individual intake and exhaust camshafts, larger valves than previous designs and four valves per cylinder--delivers more precise valve timing and more efficient exchange of intake and exhaust gases, for responsive power and increased fuel economy.

Reliability & Durability

• LESS MOVING PARTS: A Kevlar®-infused, cogged, single timing belt and chain-synchronized dual overhead camshafts provide plenty of power, and reliability with fewer moving parts. Automatic belt tensioners keep proper belt tension, avoiding adjustments for added convenience.
• CLEANER FUEL: A large, on-engine water separating fuel filter with a water sensor works in conjuction with Yamaha's 10-Micron Water Separating Fuel Filter to separate water and contaminants from the fuel before they can reach the outboard's other filters and fuel injectors.
• SMOOTH AND QUIET: A labyrinth exhaust routes gases through a maze before they exit above the water line through an idle exhaust relief outlet. This, combined with a mufflerless design, results in unbelievably smooth and quiet operation, with a pleasing sound of power at idle.
• CORROSION PROTECTION: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha V MAX SHO® engines.
• PROTECTION AND POWER: V MAX SHO® outboards have an exhaust pressure reduction system, which not only helps keep the propeller hub cooled from hot exhaust gases, but also helps provide power by transitioning those gases out of the engine during the critical hole shot and acceleration phases.
