Yamaha In-Line Four Stroke Outboard Series
In the 1950's, Genichi Kawakami was searching for a way to make use of the idle machining equipment that had been used to manufacturer airplane propellers. He started Yamaha with a focus on motorcycles and then soon turned to outboards. Now the company has about 30% of the market, and for good reason. Take their In-Line 4 Stroke. It's a "Best Of" pick because of its great fuel economy and overall performance. Six sensors help the onboard microcomputer optimize engine timing, as well as balance the ideal air/fuel mixture. Twin high-speed fuel pumps pressurize the fuel for even better efficiency. What also helps this engine perform well is a separator that removes vapors from the fuel. A front mounted flush system that makes it much easier to flush the motor, whether on the trail or in the slip. Your fellow boaters will be envious. This is one smart motor that certainly floats to the top.
