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.
