I-4 VMAX SHO® 90 HP

Outboard
Overview

The All-New VF90 In-Line Four V MAX SHO. A single-overhead-camshaft design with four valves per cylinder and 1.8-liter displacement makes the In-Line Four V MAX SHO 90 a class leader in torque, top speed and efficiency. Still, it's one of the quietest 90-horsepower outboards on the water. That makes for some pretty stealthy fishing.
