You live for the weekends. The boat’s hitched, the gear is loaded and you know exactly where you’re headed to fish. Whether there are snook and redfish, bass or walleye on the agenda, the In-Line Four V MAX SHO® is game. Available in 175, 150, 115 and 90 horsepower, this powerful In-Line Four series sports a sleek, new V6 V MAX SHO®-inspired cowling design for 2024. It also offers a surprising tech package for maximum efficiency and high performance, and the option of a 25-inch shaft for deeper waters. This makes the I-4 V MAX SHOs perfect, no matter what kind of fishing you love.

The In-Line Four V MAX SHO® 115 is Yamaha’s fastest 115-hp four stroke, ever, with a top speed of nearly 51 mph.* On top of its impressive speed, it features tech unheard of in its class, including a long-track intake system, free-flow exhaust and knock sensor.

  • 1.8-liter high-output four cylinder
  • 377 lbs. dry weight
  • Shaft lengths available: 20” and 25”

Power and Performance

Quiet Power and Performance

The In-Line Four V MAX SHO® design maximizes combustion efficiency in a way that no two stroke can, delivering clean, quiet power and performance.

Midrange Power and Response

The V MAX SHO® 175 and 150 feature Variable Camshaft Timing, which optimizes the angle of the intake camshaft to increase power and throttle response in the low- and mid-RPM ranges.

Fuel Efficient

In-line Four V MAX SHO® designs are up to 40% more fuel efficient than traditional carbureted two strokes.

Convenience and Control

AMPLE CHARGING POWER

With 50 amps for the In-Line Four V MAX SHO 175 and 150, and 35 amps for the 115 and 90, their alternators produce enough power for battery charging and a range of on-board electronics.

EASY RIGGING

In-Line Four V MAX SHO® outboards feature mechanical controls for easy, convenient rigging with most bass, bay and flats boats, and are compatible with analog, 6Y5 digital or Command Link® gauges.

NEW Tilt Stop Lever

The In-line Four V MAX SHO® 175 and 150 now feature a tilt stop lever, relieving the pressure on your hydraulics during maintenance, trailering or extended storage.
