Yamaha 200, 225 and 250 SHO Four Stroke Outboard Motors -  The all new 4.2 liter 535 lb. high output outboard engine is a game changer in the bass and flats boat world. Now anglers and pleasure boaters can have a 4 stroke outboard engine with the weight of a 2 stroke outboard. Fuel Economy on the new SHO outboards is 12% more efficient over the 2 stroke HPDI series. The Yamaha SHO is quiet, looks good, and has the hole shot to back it up. Comes in 20" Shaft length and has low water pick up built into the nose cone. The Yamaha SHO's can use wither analog or digital gauges, standard cable control boxes and remote steering systems. Here at Performance Marine we have ran and tested several of the new SHO outboards and are very pleased with the performance, acceleration and top end speeds.
