Power your vessel with the Yamaha F300 300HP Outboard Motor, engineered to deliver powerful offshore performance, responsive acceleration, and dependable operation for demanding marine applications. Known for its impressive power-to-weight characteristics and proven V6 platform, the Yamaha F300 is an excellent choice for compatible offshore fishing boats, center consoles, dual consoles, and other vessels designed for 300HP propulsion.
The Yamaha F300 features a 4.2-liter V6 four-stroke engine with electronic fuel injection and Yamaha’s advanced engine technology. Producing 300 horsepower at 5,500 RPM, it delivers the power and performance needed for serious offshore boating while maintaining practical fuel efficiency for its horsepower class.
Updated digital-control configurations feature a refreshed cowling design, integrated digital electric steering, and rerouted exhaust intended to enhance reverse thrust. When properly configured with the compatible Helm Master EX system, engine-mounted Propeller Indicator Lights can provide additional directional information. These lights depend on the specified Helm Master EX rigging and should not be assumed to be included with every engine.
The F300 is available with 25-inch, 30-inch, and 35-inch shaft options, with the 30-inch and 35-inch configurations available on the digital electronic control models. Model-specific shaft lengths and finishes allow buyers to select an appropriate engine for their vessel.
Color choices include Yamaha’s signature gray, pearlescent white, and classic white on specified digital models. The mechanical-control F300 remains a separate configuration and is available in gray according to Yamaha’s published specifications.
The engine also features an alternator output of up to 70 amps, electric starting, power trim and tilt, and Yamaha’s recommended 89-octane fuel specification. These features make the F300 a practical option for boat owners who need substantial power for offshore cruising, fishing, and compatible recreational marine applications.
Before ordering, confirm the exact engine model, shaft length, control type, steering system, rotation, color, and required rigging components.

Why Choose the Yamaha F300 300HP?
The Yamaha F300 300HP Outboard Motor is designed for boat owners who need powerful and dependable performance for offshore and recreational boating. Its 4.2-liter V6 engine provides substantial horsepower, while electronic fuel injection supports controlled fuel delivery and responsive operation.
Updated digital models provide integrated digital electric steering, which is designed to simplify steering integration and support compatible electronic control systems. The refreshed cowling and rerouted exhaust add to the updated engine configuration, with enhanced reverse thrust intended to assist maneuvering.
The multiple shaft-length options allow customers to select a configuration suited to their boat’s transom requirements. The availability of Yamaha Gray, Pearl White, and Classic White finishes on specified digital models also provides flexibility when matching an engine to a vessel.
With electric starting, power trim and tilt, and alternator output of up to 70 amps, the Yamaha F300 is well suited to compatible boats equipped for serious fishing, offshore cruising, and recreational use.
4.2-Liter V6 Engine
The Yamaha F300 uses a 4.2-liter V6 four-stroke engine designed to provide high horsepower without unnecessarily increasing engine size and weight.
Its electronic fuel injection system controls fuel delivery according to operating conditions. Yamaha’s V6 offshore engine design incorporates technology intended to reduce friction, support cooling, and provide responsive power delivery.
With 300 horsepower available at 5,500 RPM and a full-throttle range of 5,000–6,000 RPM, the F300 is engineered for vessels that require substantial propulsion for offshore operation.
Integrated Digital Electric Steering and Updated Cowling
Specified digital electronic control models feature a refreshed cowling and integrated digital electric steering. The integrated steering system is designed to provide a streamlined steering arrangement compatible with the applicable Yamaha electronic controls and rigging.
The engine-mounted Propeller Indicator Lights referenced in Yamaha’s updated product information apply when the engine is correctly configured with Helm Master EX. Confirm the compatible system, required equipment, and actual package contents before purchase.
Important: Yamaha states that mechanical F300 models remain unchanged and are available in gray only. The updated steering features should therefore be matched to the correct digital model rather than automatically attributed to the mechanical version.
25-Inch, 30-Inch, and 35-Inch Shaft Options
The Yamaha F300 is offered in different shaft lengths for compatible vessel configurations.
25-inch shaft: Available on the mechanical F300XA and specified digital models.
30-inch shaft: Available on specified digital electronic control models.
35-inch shaft: Available on specified digital electronic control models.
The correct shaft length depends on the boat’s transom height and manufacturer’s requirements. Check shaft compatibility before ordering to help ensure proper engine mounting and operation.
Mechanical and Digital Electronic Controls
The Yamaha F300 range includes mechanical-control and digital electronic control configurations.
Mechanical model: The F300XA is a 25-inch shaft model in Yamaha Gray with remote mechanical controls. It represents the unchanged mechanical-control configuration.
Digital models: Specified F300 DEC models support digital control systems and offer different shaft lengths and finishes. Updated models with integrated digital electric steering should be selected by the exact model code.
Control boxes, steering components, wiring harnesses, gauges, propellers, and other rigging equipment should be confirmed separately unless explicitly included in the sale.
Alternator and Onboard Electronics
The Yamaha F300 features alternator output of 50–70 amps, with up to 70 amps available, depending on operating conditions and configuration.
This charging capacity can support the starting battery and compatible onboard electronics, including navigation displays, fish finders, communications equipment, and other marine accessories. Actual available charging output depends on engine speed, electrical loads, and the boat’s electrical installation.
Recommended 89-Octane Fuel
Yamaha recommends 89-octane fuel for the F300 4.2L V6 Offshore engine.
Using the recommended fuel grade and following Yamaha’s service schedule are important for proper operation. Buyers should consult the applicable owner’s manual for detailed fuel, maintenance, storage, and operating requirements.
Power Trim & Tilt
The listed Yamaha F300 configurations feature power trim and tilt. This system allows the operator to adjust the outboard’s angle for different running conditions, launching, shallow-water positioning where appropriate, and storage.
The trim system should be paired with the correct controls and electrical connections for the selected engine model.
Available Colors
The Yamaha F300 range offers the following finishes on specified model configurations:
Yamaha Gray: Available on the mechanical F300XA and specified digital models.
Pearl White: Available on specified digital models.
Classic White: Available on specified digital models.
Color and shaft availability depend on the exact model code. Confirm the chosen finish and configuration before placing an order.
Ideal Applications
The Yamaha F300 may be suitable for compatible offshore fishing boats, center consoles, dual consoles, walkaround boats, larger recreational vessels, and other boats designed for 300HP outboard propulsion.
The correct engine depends on the boat manufacturer’s maximum horsepower rating, transom height, weight limits, steering arrangement, control requirements, and intended use. Twin-engine installations also require the correct standard-rotation and counter-rotation selection where applicable.
Always verify boat and engine compatibility with a qualified marine professional before purchasing or installing the outboard.
