Yamaha F150 Engines Revealed With Integrated Steering
The Yamaha F150 has enjoyed more than a decade of unrivaled popularity.yamaha f150 Powerful, light and compact, its proven reliability is a good fit for a wide variety of boat styles and hulls. Designed to meet new emissions regulations, the engine has evolved and is now offered with integrated steering for even greater performance and convenience.
The engine features an electronic throttle valve working in harmony with the multiport fuel injection and ignition systems to achieve excellent performance, fuel economy and emissions compliance.yamaha f150 Unlike many other 150hp four-strokes, the F150 also has variable camshaft timing for increased low and mid-range torque. Its compact powerhead design makes it possible to install the engine on smaller boats, and its offset crankshaft contributes to a more efficient transfer of power to the propeller.
Two models are available: The standard F150B with mechanical controls and the uprated F150DEC with digital shift.yamaha f150 Both use the same powerhead as the larger F175 and F200, but with different configurations to suit each application. The F150DEC takes advantage of Yamaha’s premium Digital Electronic Control (DEC) technology, which brings “fly-by-wire” control to the smaller engine class.
This patented system eliminates the need for cables by sending engine data to a computer, which then adjusts the carburetors and spark plugs in real-time to deliver the exact amount of power needed at any given time.yamaha f150 Compared to the traditional cable-actuated system, this new digital design offers faster, smoother and more precise throttle operation.
Both the F150B and the F150DEC are compatible with Yamaha’s Shift Dampener System for a quieter, more comfortable gearshift.yamaha f150 They are also compatible with the NMEA2000 protocol for running third-party displays, and the F150DEC is compatible with Yamaha’s Command Link Plus digital instrumentation.
Both engines are designed to provide the maximum level of fuel efficiency without compromising engine performance or durability. They are capable of running on 87-octane fuel, and their high gear ratios mean they can spin the prop at lower RPMs to get maximum acceleration from any speed.
The cylinder head is designed with dual camshafts and 16 valves, which provides plenty of torque and displacement at W.O.T. The powerhead is slim in design and the cylinders are arranged to allow for either single or twin-engine installations. The engines are also compatible with Yamaha’s Helm Master EX autopilot and Joystick, for the ultimate in onboard control.
All F150 Digital and Mechanical-Control models are now available with integrated steering, which is integrated into the cylinder unit rather than being a separate bolt-on component. This helps to simplify rigging and keep the bilge area clear for easier maintenance. The Integrated Steering models are also fully compatible with Yamaha’s exclusive Helm Master EX autopilot and joystick system, making them perfect for new high-tech boat packages and existing boat repowers alike.
