FAST + Light + Fuel Efficient


For years, bass anglers championed the two stroke, sacrificing fuel economy and power for performance. That is, until Yamaha unleashed the world’s first 4.2L Super High Output four stroke for bass boats. The four stroke V MAX SHO® offers all the advantages of a two stroke in a clean burning, fuel efficient four stroke. It’s a level of performance that pro anglers have always wanted on the tournament circuit. And it’s officially put two strokes on notice.


V MAX SHO® Models: vF250 | vF225 | vF200

A MotorBoating Best Of in 2009 and 2010, the Four Stroke V MAX SHO® features:

Lightning-Fast Hole Shot
The V MAX SHO® has a 4.2L big-bore design that shoots it out of the hole up to 13% faster than its two stroke competitors. Its variable camshaft timing increases throttle response in the low and midranges, resulting in unbelievable acceleration, top-end and midrange punch.

Brute Strength
Its 4.2L big-bore design gives the V MAX SHO® class-leading displacement and power-to-weight ratio.

Smart Innovations
Micro-textured cylinder walls and a new intake system greatly improve fuel economy. In fact the V MAX SHO® boasts up to 12% better fuel economy than competitive two strokes, and is C.A.R.B. 3-Star Rated for Ultra Low Emissions

Lightweight Design
Yamaha engineers redesigned the cowling, engine bracket and lower engine pan, shaving every ounce of weight, without compromising durability. As a result, the V MAX SHO® is just 505 pounds (dry weight)—a good 34 pounds lighter than previous two stroke V MAX designs.

Take a look at the game-changing innovation inside the Yamaha 4.2L four stroke V MAX SHO®.

“…fuel savings means money back in my pocket—to the tune of about $40 a day in oil and fuel. I don’t know a guy out there who wouldn’t appreciate that.”
