Suzuki Engineers labored through years of trial and success with computer simulations and on water testing to significantly improve the way an outboard motor converts engine power to underwater thrust. Once you have all of that horsepower, now the challenge is getting it to hook up or grab traction in the water. While adding complex mechanical components can create reliability concerns. However, larger displacement engines typically burn more fuel and increase the overall weight. The engine design can include larger displacement and adding turbo chargers or superchargers. Making more horsepower can be accomplished in many ways. In developing the new DF350A, Suzuki Engineers started with a clean sheet of paper and considered many factors for this design. Suzuki has embarked on a major engineering expedition to build the Ultimate Outboard Motor. As more powerful outboards are introduced, the boats get bigger and as the boats get bigger, outboards are getting more muscular. These new outboard motors have fueled a demand for larger boat designs that previously may have been powered by stern drive or other inboard power. It's no secret that there is a growing demand for more powerful outboard motors.
