I-4 VMAX SHO® 90 HP

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.
- Only 353 pounds

- Shaft lengths available: 20” and 25”
- 35 amps of charging power
- Optional Variable Trolling RPM via gauge or remote switch
