2017 Yamaha VF150X VMAX SHO Outboard Motor

This 2017 Yamaha VF150X is the base trim of Yamaha's in-line four V MAX SHO, new, rated 150 HP at 5,500 RPM from a 2.8-liter four-cylinder. Where the XA trim adds certain convenience features, this base build keeps the same core engine at a simpler spec level.

Engine architecture

Double overhead camshafts work four large-radius valves per cylinder, and variable camshaft timing shifts the intake-cam angle to help response across everyday RPM rather than only at full throttle. A long-track induction system paired with four injectors keeps breathing efficient across the 16-valve head.
