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—and a day out fishing.
