The all-new Yamaha 90 hp and 75 hp Midrange four strokes are engineering achievements. Lighter, faster and more powerful than their previous designs, they sport SOHC four-valve-per-cylinder designs that increase volumetric efficiency. They also save weight—13 pounds to be exact. At the same time, they’ve both stepped up to 1.8-liter displacement. Lighter weights, plus more power, creates a thrilling new F75, and makes the F90 a top performer in torque and acceleration. The F90 also features a 25-inch shaft option, which makes it prime power for a range of mid-size boaters and of particular interest to inshore anglers trolling for walleye or muskie on 25-inch-transom multi-species boats. The completely re-engineered Yamaha F75 and F90 Midrange four strokes. Powerful new additions to our lineup—and your boating experience.
