Power your boat with the Yamaha F25 25HP Outboard Motor, engineered to deliver reliable power, lightweight portability, and efficient performance for fishing, recreational boating, and utility applications.
The Yamaha F25 features a 432cc two-cylinder engine with battery-less electronic fuel injection (EFI). Its streamlined design combines a strong power-to-weight ratio with responsive operation, making it an appealing choice for boat owners who need 25HP performance without the bulk of a larger outboard.
The engine is available in 15-inch and 20-inch shaft configurations for standard F25 models. A separate T25 High-Thrust range provides additional configurations, including 20-inch and 25-inch shaft options for compatible applications.
Depending on the selected model, the F25 is available with manual starting, electric and manual starting, tiller steering, remote mechanical controls, and power trim and tilt.
The engine’s 16-amp alternator supplies charging power for compatible electrical equipment. Its battery-less EFI system also allows pull-start configurations to use electronic fuel injection without requiring a starting battery.
Selected versions feature a shorter, tilting tiller handle with integrated trim controls, making them especially practical for boats where compact storage and maneuverability matter.
Available finishes include Yamaha Gray, Pearl White, and Matte Brown on selected models, allowing customers to choose a configuration suited to their boat.

Why Choose the Yamaha F25 25HP?
The Yamaha F25 25HP Outboard Motor is designed for boaters who need portable power, efficient fuel delivery, and flexible rigging options.
Its 432cc engine and battery-less EFI system provide modern fuel-injection technology in a compact outboard package. Depending on the model, customers can choose manual starting, electric starting, tiller operation, remote controls, and power trim and tilt.
The lightweight design makes the F25 particularly useful for compatible aluminum fishing boats, jon boats, tenders, inflatables, skiffs, and other smaller vessels.
Customers who need additional thrust for a particular boat or application can also consider the dedicated T25 High-Thrust models, subject to vessel compatibility.
432cc Battery-Less EFI Engine
The Yamaha F25 uses a 432cc two-cylinder, four-stroke engine with electronic fuel injection.
Battery-less EFI allows compatible pull-start models to benefit from fuel injection without requiring a battery for the EFI system to operate. Yamaha also incorporates an automatic decompression device designed to reduce the effort required for manual starting.
This provides a practical combination of modern engine technology and convenient operation for portable marine applications.
Lightweight and Portable Design
Selected Yamaha F25 configurations weigh approximately 126 pounds with a 15-inch shaft.
The compact design and convenient carrying features make the engine suitable for boat owners who need a portable outboard for small fishing boats, tenders, inflatables, and other compatible vessels.
Actual weight varies by shaft length, trim system, starting configuration, and controls.
15-Inch and 20-Inch Shaft Options
Standard Yamaha F25 outboards are offered with either a 15-inch or 20-inch shaft.
The separate T25 High-Thrust lineup includes selected 20-inch and 25-inch shaft configurations, giving customers further flexibility for compatible vessels.
Choosing the correct shaft length is essential for proper mounting and engine operation. Customers should verify transom height and the boat manufacturer’s recommended shaft length before ordering.
T25 High-Thrust Option
The Yamaha T25 High-Thrust Outboard is designed for applications that require the appropriate high-thrust configuration.
Listed T25 models feature a Dual Thrust propeller and high-thrust lower unit, with 20-inch and 25-inch shaft options available in selected configurations.
Customers should confirm that a T25 High-Thrust model is suitable for their boat and intended use before purchasing.
16-Amp Charging System
The Yamaha F25 features a 16-amp alternator output at wide-open throttle.
This provides charging capability for compatible electrical systems and helps support practical marine use. Actual charging output depends on engine speed and the electrical load.
Variable Trolling RPM
The Variable Trolling RPM Switch (VTS) provides a way to adjust trolling speed in compatible configurations, depending on the selected controls and rigging.
This feature can be helpful for anglers who need to maintain a controlled, low speed while fishing. Customers should confirm which compatible equipment is required for their chosen engine.
Tiller, Remote Controls and Power Trim & Tilt
Yamaha offers the F25 in different control configurations.
Tiller models provide direct steering and throttle operation at the engine. Selected models have power trim and tilt and a shorter, tilting tiller handle with integrated trim controls.
Remote-control models are designed for operation from a compatible helm and are available with different starting and trim arrangements.
Customers should select the appropriate combination of controls, starting system, trim equipment, and shaft length for their boat.
Color and Configuration Options
Selected Yamaha F25 models are available in Yamaha Gray, Pearl White, and Matte Brown.
Color availability depends on the model and equipment configuration. The available shaft length, controls, starting system, and trim features should be confirmed when selecting a specific model.
Ideal Applications
The Yamaha F25 25HP may be suitable for compatible:
Aluminum fishing boats, jon boats, small fishing boats, tenders, inflatables, skiffs, utility boats, recreational vessels, and other craft designed for a 25HP outboard.
T25 High-Thrust models may suit other applications requiring the appropriate high-thrust configuration.
Always confirm the vessel’s horsepower rating, transom requirements, shaft length, steering and control system, and intended operating conditions before purchase.
