THE ALL-NEW

IN-LINE FOUR

V MAX SHO® 90

The all-new Yamaha 90-horsepower In-Line Four V MAX SHO® may be the smallest in the V MAX SHO® line, but it packs the biggest punch of any 90-horse on the water. Its SOHC four-valve-per-cylinder design minimizes weight while optimizing combustion. In fact, its lightweight design combined with 1.8L displacement makes the I-4 V MAX SHO® 90 the class leader in torque and top speed. Add to that the option of a 25-inch shaft and the VF90 is an exciting new prospect for bass, walleye, inshore and muskie anglers trolling on 25-inch transom multi-species boats. The all-new Yamaha I-4 V MAX SHO® 90. A quick, little addition to our V MAX SHO family&mdash;and a day out fishing.

STEALTHY & STREAMLINED

The all-new I-4 V MAX SHO 90 is not only the fastest on the water; it’s also the quietest. In fact, it’s noticeably quieter than its closest competitor. It gets even smoother and quieter still when you add a Yamaha propeller with our patented Shift Dampener System (SDS). Talk about stealthy fishing.

Lightweight & Compact Design


The I-4 V MAX SHO 90 features a single overhead camshaft with four valves per cylinder, for 16 total valves. (Its primary competitor only features eight valves.) This optimizes engine combustion, and creates class-leading torque and acceleration, all while reducing mass in the cylinder head and streamlining weight.
