This is a 2.8L 150 VMAX SHO which descends from the original 2.7 F150, which was launched in 2003. The F150 was a whole new direction for Yamaha and led to all 4 cylinder four stroke engines from 150 to 200, as well as inspired the 90 and 115 four stroke, and the 4.2 V6. The F150 was a game changer.
