For sheer unbridled power, speed and performance, Yamaha’s VF250 Vmax SHO (Super High Output) four-stroke outboards deliver where no other four-stroke or two-stroke can. This race bred outboard has been purposely designed to meet the competitive needs of bass boat fishing, skiing, racing and other adrenalin packed boating activities. The 4.2 litre, 24-valve, double overhead cam engine is not only extremely compact, but is lighter than another equivalent four-stroke on the market. The secret to its performance is the plasma-fused sleeveless cylinders which significantly reduce the overall weight while increasing the engine capacity. If speed is your thing, then there is no better option.
