Power your boat with the Yamaha F40 40HP Outboard Motor, engineered to deliver responsive acceleration, efficient fuel consumption, dependable operation, and impressive top-end performance in a compact marine package.
The Yamaha F40 features a 747cc three-cylinder engine with a single-overhead-camshaft design, a long-track intake manifold, and electronic fuel injection. Yamaha’s engine management system is designed to support easy starting, smooth operation, and responsive power delivery.
This 40HP midrange outboard is available in both standard propeller-driven and jet-drive configurations, providing flexibility for different boating applications. Standard propeller models use a 20-inch shaft and are offered with tiller or remote mechanical controls, depending on the selected model.
The F40 produces 40HP at the propeller shaft in the standard propeller-driven configuration. The jet-drive models use a jet pump and are listed at 30HP jet-drive output, which should be considered when comparing performance and selecting an engine for a particular vessel.
The engine features a 17-amp alternator, providing charging capacity for compatible batteries and onboard electrical equipment. It also uses electronic fuel injection and has a recommended minimum fuel octane of 87.
With a listed weight range of approximately 214–223 pounds, depending on the configuration, the Yamaha F40 is a practical option for compatible aluminum fishing boats, skiffs, jon boats, inflatables, small pontoons, utility boats, and other lightweight craft.

Why Choose the Yamaha F40 40HP?
The Yamaha F40 40HP Outboard Motor is designed for boat owners who want useful horsepower, efficient fuel delivery, and versatile configuration choices.
Its 747cc three-cylinder engine provides a practical balance of power, compact dimensions, and responsive performance. Electronic fuel injection supports dependable starting and fuel delivery, while the 17-amp alternator provides charging capacity for compatible onboard electrical systems.
The availability of both propeller-driven and jet-drive models makes the F40 lineup suitable for different vessel designs and operating requirements.
Customers can also choose between tiller and remote mechanical controls, depending on the selected engine model and their intended installation.
747cc Three-Cylinder EFI Engine
The Yamaha F40 uses a 747cc three-cylinder four-stroke engine with electronic fuel injection.
Its single-overhead-camshaft design and long-track intake manifold are engineered to support efficient operation, responsive throttle performance, and strong acceleration.
Electronic fuel injection manages fuel delivery for consistent engine operation. Customers should follow Yamaha’s recommended fuel specifications, service intervals, and operating instructions.
40HP Standard Propeller Performance
The standard Yamaha F40 40HP Outboard delivers 40 horsepower at the propeller shaft.
This configuration is suitable for compatible boats requiring a conventional propeller-driven outboard. The engine’s 747cc three-cylinder design, EFI system, and intake configuration are intended to provide responsive power for fishing and recreational applications.
Actual boat speed and acceleration depend on hull design, propeller selection, boat weight, load, water conditions, and engine setup.
Jet-Drive Option
The Yamaha F40 Jet Drive is available for applications requiring jet propulsion rather than a conventional propeller.
The listed F40 jet models use a 20-inch shaft and offer either tiller or remote mechanical controls. Yamaha lists their output as 30HP at the jet drive.
Jet propulsion may be suitable for certain shallow-water and debris-prone applications, depending on the vessel, operating conditions, and manufacturer’s guidance. Customers should confirm that the jet-drive configuration meets their boat’s performance and installation requirements before purchasing.
20-Inch Shaft Configuration
The Yamaha F40 Midrange Outboard features a 20-inch shaft configuration in the listed models.
Correct shaft length is essential for proper outboard mounting and operation. Customers should verify their vessel’s transom height and manufacturer’s recommended shaft length before ordering.
17-Amp Charging System
The Yamaha F40 features a 17-amp alternator, providing charging capacity for the starting battery and compatible onboard electrical accessories.
This capability can help support electrical equipment used on fishing boats and recreational vessels. Actual charging output varies with engine speed and electrical load.
Tiller or Remote Mechanical Controls
The Yamaha F40 is offered with different control configurations, depending on the selected model.
Tiller-control versions allow the operator to steer and control the engine directly at the outboard.
Remote mechanical-control versions are designed for operation from the helm of a compatible boat.
Customers should select the control arrangement that suits their vessel and confirm which cables, controls, steering components, and rigging hardware are included or required.
Power Trim & Tilt or Nitro-Assist Tilt
Selected standard propeller-driven F40 models feature power trim and tilt, while the listed tiller and jet models may use Nitro-Assist Tilt.
The precise trim and tilt arrangement depends on the selected model. Customers should confirm the model code and standard equipment before ordering rather than assuming every F40 includes power trim and tilt.
Optional Variable Trolling RPM
The Variable Trolling RPM Switch (VTS) is an optional feature available subject to compatible engine rigging and equipment.
This feature can help anglers adjust engine speed during slow-speed fishing, making it useful for applications where maintaining a consistent trolling speed matters.
Customers should confirm the required switch, gauge, and compatible configuration before purchasing the optional feature.
Ideal Applications
This Yamaha F40 40HP Outboard Motor may be suitable for compatible:
Aluminum fishing boats, jon boats, skiffs, small center consoles, inflatables, small pontoons, utility boats, recreational vessels, and other boats designed for a 40HP propeller-driven outboard.
The jet-drive version may suit compatible vessels designed specifically for jet propulsion.
Always verify the vessel’s horsepower rating, shaft requirements, mounting configuration, propulsion type, controls, steering arrangement, and operating conditions before purchase.
