Yamaha F175 I-4 2.8L Mechanical 25 in. for Sale

Convenience & Control

• REPOWER READY: 26-inch mounting centers and a bolt pattern that matches previous two strokes make In-Line Fours flexible for most repowers.
• VARIABLE TROLLING: Our entire I-4 series has a user adjustable trolling speed. This allows for precision adjustment of trolling in 50-RPM increments when equipped with a Yamaha digital gauge. Trolling range varies based on model.
• EXTENDED TRIM: Extended Trim Range delivers better acceleration-to-plane and top-end speed. The tilt range is a full 70° for tilting the engine above the waterline.
• EASY ENGINE FLUSHING: A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
• QUIETER OPERATION: Yamaha's Shift Dampener System greatly reduces the noise commonly associated with shifting gears. Using a special design and components, much of the force of shifting is absorbed, resulting in far quieter and smoother operation.

Features

• COMPATIBLE CONTROLS FOR EVERY PLATFORM: Now, the F200, F175 and F150 are available with either digital or mechanical controls and even our next generation boat control system Helm Master® EX.

Power & Performance

• IMPRESSIVE POWER-TO-WEIGHT: A proven 16-valve DOHC In-Line design, with four valves per cylinder maximizes efficiency and power. It also streamlines design, giving the F200 class-leading power-to-weight and making the F175 nearly 30 pounds lighter than its closest 1.7-liter competitor.
• OPTIMUM POWER: Precision Multi-Point Electronic Fuel Injection and long-track intake system combine to maximize power and fuel efficiency across the line of In-Line Fours (except F150 Mechanical).
• QUICK ACCELERATION: A 10mm Offset Crankshaft allows for larger intake volume design. Four tuned intake tubes boost torque in low and mid-speed ranges for quick acceleration.
• POWERFUL HOLE SHOT: The Composite Intake Manifold is a lightweight, compact design, making these engines very versatile. Long Tube Intake Tracks are tuned to increase airflow, boosting low-end and midrange torque. This means a more powerful hole shot and increased acceleration. Even with all this responsive power, an air silencer box and surge tank reduce air intake noise and air turbulence for smoother operation.

Reliability & Durability

• PROTECTION FROM THE ELEMENTS: All Yamaha In-Line Four models feature a proven cowling drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that trap and drain water before it enters the engine's intake, for maximum reliabilty.
• MINIMAL VIBRATION: Twin counterbalancing shafts minimize engine vibration for a smooth ride.
• CORROSION RESISTANCE: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha In-Line Four-Stroke engines.
• BETTER LUBRICATION: Wet sump pump lubrication that uses a pressurized oil delivery system through an oil pump.
• TO-THE-SECOND TIMING: Wet sump pump lubrication that uses a pressurized oil delivery system through an oil pump.
