Evinrude got things rolling with the next-generation E-TEC G2 direct-injection two-strokes with a new block and piston/cylinder design to enhance combustion and improve fuel economy. Other manufacturers quickly followed suit. Yamaha is expanding its V Max SHO line of four-strokes by shedding weight and adding torque and power. The result is better top-end speed, better fuel efficiency and more rigging and control options, especially for midsize center-consoles, bay and flats boats. Not to be outdone, Suzuki introduced the DF200AP at the Miami International Boat Show, an inline four-cylinder four-stroke with a keyless starting system, electronic throttle and shift and selectable rotation. Its semi-direct air intake shunts cool air into the manifold, which improves acceleration and speed.
