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 make the I-4 V MAX SHO 90 a class leader in torque, top speed and efficiency. But it’s not only the fastest—it’s the quietest, too.* That makes for some pretty stealthy fishing.
