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 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.
Available for mechanical remote or tiller control.
- Only 353 pounds
- Available in 20” or 25” shafts
- Powerful 35-amp alternator
- Optional Variable Trolling RPM via the Command Link tachometer or our new, helm-mounted remote VTS® Switch
*Testing conducted by Yamaha at Yamaha’s US Test Facility on a G3 Eagle Talon™ under the same conditions and with each rigged for maximum performance.
