Used Yamaha 40HP – 20″ Shaft, 2016 Model

Used Yamaha 40HP 4-Stroke Outboard (20″ Shaft)

Overview This used Yamaha 40HP midrange 4-stroke is a fantastic choice if you need reliable power without the bulk. Known for its compact size and solid performance, it is a perfect match for skiffs, aluminum fishing boats, and other light-duty vessels.

At its core is a 3-cylinder engine featuring single-overhead camshafts and electronic fuel injection (EFI). This combination gives you quick, dependable starts, responsive acceleration, and impressive fuel efficiency—all while running quietly. It is also compatible with Yamaha’s Multi-Function Tiller Handle, giving you great flexibility for trolling and general maneuvering.  

Key Features & Benefits

• Fuel Economy: The Precision Multi-Point EFI system delivers exactly the right amount of fuel for the conditions, optimizing atomization to save you gas without sacrificing performance.  

• Compact Design: The 3-cylinder, Single Overhead Camshaft (SOHC) design keeps the engine lightweight and space-saving, ideal for smaller transoms.  

• Dependable Starting: Thanks to a vapor-reducing fuel return system and EFI, this motor offers turn-key starting reliability in both hot and cold weather.  

• Precise Control: A single throttle valve routes air through “pulse-tuned” long intake tracks, ensuring the engine gets the precise volume of air needed for maximum density and power.  

• Corrosion Protection: Yamaha’s exclusive Phaze Five™ paint system and proprietary YDC-30 alloy create a tough, five-layer barrier against the elements.  

• Easy Maintenance: A Freshwater Flush Device lets you flush the cooling system without running the engine, extending its life and making cleanup easy.  

Convenience & Technology

• Smart Diagnostics: The Engine Control Module connects with Yamaha Diagnostic System software, allowing technicians to view past and current running data for accurate servicing.

• Water Protection: The one-piece cowling features an intake drain system with labyrinth passages to trap and drain water before it can enter the engine intake.
