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.

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.
Cleaner Fuel: Includes a large on-engine water-separating fuel filter with a water sensor to protect injectors and filters from contaminants.
