Yamaha F300ESB 300HP Outboard – 25in Shaft, Digital Electronic Steering

Heavy twin-engine coastal vessels track dead straight when the Yamaha F300ESB engages its integrated digital electric steering. The massive 4169cc V6 block breathes enormous volumes of air, translating fly-by-wire inputs into explosive acceleration to launch heavy fiberglass center consoles onto plane flawlessly. Verifying your twin-engine bracket guarantees this digital steer 300hp outboard motor aligns securely without starving the internal water pump.

Eradicate exhausting mechanical steering friction at high speeds by utilizing the built-in digital steering compatibility as a direct handling upgrade. You pilot fast twin-engine rigs with absolute single-finger precision without fighting stiff physical hydraulic cylinders. Yamaha casts the 267 kg assembly using specialized anti-corrosion marine aluminum. This structural barrier stops rapid galvanic decay when repowering luxury offshore yachts in high-salinity coastal environments.

Key Features of Yamaha F300ESB

- Integrated Digital Electric Steering (DES): Eliminates messy external hydraulic cylinders and pumps, delivering sports-car-like handling and zero steering fatigue during long runs.
- Digital Electronic Control (DEC): Translates hand movements into instant electronic commands, eliminating mechanical cable slop during precise marina maneuvering.
- 4.2-Liter DOHC Block: Delivers brutal low-end torque from a massive 4169cc displacement, lifting heavy fiberglass hulls onto plane instantly.
- 25-Inch Extra-Long Shaft: Fits elevated high-performance transoms perfectly, keeping the gearcase profile tight to maximize top-end running speeds.
- 50-70 Amp High-Output Alternator: Generates massive electrical current continuously, keeping deep cycle house batteries fully charged for heavy-duty marine electronics.
- 1.75:1 High-Speed Gearcase: Spins aggressive high-pitch propellers efficiently, translating massive big block torque directly into forward vessel momentum.
- Electronic Fuel Injection (EFI): Calculates precise fuel requirements continuously, eliminating carburetor hesitation and ensuring crisp acceleration across the RPM band.
- Hydraulic Power Trim: Adjusts the running angle dynamically via the binnacle switch, optimizing bow attitude across aggressive offshore swells.
- Anti-Corrosion Castings: Blocks severe galvanic decay physically, protecting the aluminum powerhead block across decades of daily saltwater exposure.
- Clean Four-Stroke Combustion: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.

Why Choose Yamaha F300ESB

This advanced 25-inch block acts strictly as a high-end fly-by-wire power plant featuring built-in electric steering. Substituting a standard mechanical control model sacrifices electronic shifting entirely. Upgrading your digital throttle syncing network is mandatory for smooth dual-engine communication.

- Verify your twin-engine transom bracket accommodates a 25-inch shaft length safely.
- Link the DEC module to your master binnacle to synchronize shift commands perfectly.
- Navigate restricted coastal fisheries legally utilizing advanced four-stroke combustion.

Ideal Application and Vessel Fitment

This 300-horsepower drive-by-wire block is engineered strictly for modern deep-V center consoles, premium fiberglass skiffs, and twin-engine coastal vessels demanding a 25-inch shaft. Operating as a highly responsive digital drive equipped with integrated DES, it translates electronic throttle data instantly, keeping twin-engine performance hulls tracking perfectly straight at high cruising speeds. It thrives in competitive offshore environments where balancing massive thrust requires precise fly-by-wire power.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited Pleasure Warranty alongside exceptional factory support. Registered commercial applications fall under a strict 1-Year Commercial Warranty with zero corrosion coverage applied to the block. Scheduled maintenance requires replacing gearcase lubricants and changing oil filters at manual-specified intervals. Always save all physical service records. Your engine serial number acts as the only way to source exact genuine replacement parts. For product details and order support, Mulmotor offers assistance before your purchase is placed.
