2017 Yamaha VF250X VMAX SHO Outboard Motor

This 2017 Yamaha VF250X is the base trim of Yamaha's 250 HP V6 V MAX SHO, a new 4.2-liter engine on a 20-inch shaft. Where the LA and XA trims add certain rigging features, this base build keeps the same core powerhead at a simpler spec.

Plasma-fused sleeveless cylinder bores, double overhead cams and four large valves per cylinder are the same architecture found across the SHO V6 range, configured here without some add-on convenience items.
