Yamaha LF300XCB 300HP Outboard – 25in Shaft, Counter Rotation

Executing flawless dock approaches in high winds requires the counter-rotating Yamaha LF300XCB to balance your thrust mechanically. The 4.2-liter V6 translates digital fly-by-wire throttle commands into explosive midrange torque, pushing heavily loaded center consoles across wide bays instantly. Verifying your twin-engine transom bracket guarantees this 25 inch digital steer counter rotating outboard aligns securely without starving the internal cooling intakes during tournament runs.

Eradicate exhausting mechanical steering friction at high speeds by integrating this digital electronic control engine into your port-side rigging network. You pilot fast twin-engine coastal vessels with absolute single-finger precision without fighting stiff physical control cables. Yamaha casts the 255 kg assembly using specialized anti-corrosion marine aluminum alloys. This structural barrier stops severe galvanic decay when finalizing a port side digital twin setup for continuous saltwater tournament use.

Key Features of Yamaha LF300XCB

- Digital Electronic Control (DEC): Translates hand movements into instant electronic commands, eliminating mechanical cable slop during precise marina maneuvering.
- Counter-Rotating Gearcase: Cancels the massive lateral thrust of a starboard engine, keeping twin-engine performance hulls tracking perfectly straight underway.
- 4.2-Liter DOHC Block: Breathes massive volumes of clean air efficiently, generating 300 horsepower effortlessly to lift heavy fiberglass hulls onto plane.
- 25-Inch Extra-Long Shaft: Drops the propeller deeply below high offshore transoms, maintaining solid forward thrust and preventing water pump starvation.
- 50-70 Amp Charging Alternator: Outputs massive charging power, keeping demanding radar systems and heavy-duty livewell pumps fully powered offshore.
- 1.75:1 High-Speed Gearcase: Spins aggressive high-pitch propellers efficiently, translating massive big block torque directly into forward vessel momentum.
- Multi-Point Sequential EFI: Calculates precise fuel requirements continuously, eliminating carburetor hesitation and providing crisp acceleration across the RPM band.
- Hydraulic Power Trim: Adjusts the running angle actively 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 LF300XCB

This advanced 25-inch block acts strictly as a high-end fly-by-wire power plant designed for the port side of dual-engine applications. Substituting a mechanical control model sacrifices electronic shifting entirely. Upgrading your electronic throttle shift 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.
- Keep coastal waters clean by running highly regulated four-stroke engine configurations.

Ideal Application and Vessel Fitment

This 300-horsepower drive-by-wire block is engineered strictly for modern deep-V center consoles, advanced fiberglass skiffs, and twin-engine coastal vessels demanding a 25-inch shaft. Operating as a highly responsive digital drive, it translates electronic throttle data instantly, keeping twin-engine performance hulls tracking perfectly straight at high cruising speeds. It thrives in competitive coastal environments where balancing massive thrust requires precise fly-by-wire power without sacrificing absolute long-term mechanical reliability.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited 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. Mulmotor provides product-information support before purchase and assistance with order-related questions.
