Yamaha has added a 90 hp engine to its V MAX SHO lineup, which previously comprised six models from 115 hp up to 250 hp. SHO engines have been popular with fishermen who need a quick hole shot and hyperacceleration. Yamaha says the 1.8-liter 90 SHO (super-high output) delivers class-leading torque and top speed. A single overhead camshaft drives four valves per cylinder to deliver more power from less weight. The mechanical 90 is compatible with Yamaha’s Command Link gauges and can be rigged for tiller control. Its quiet performance is enhanced by Yamaha’s Talon SS4 prop, featuring the company’s Shift Dampener System. The new outboard costs $10,715.
