2021 Yamaha Marine I-4 V MAX SHO® 90
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.
Features may include:- Only 353 pounds
- Available in 20” or 25” shafts
- Powerful 35-amp alternator
