Yamaha LF350XCC 350HP Outboard – 25in Shaft, Counter Rotation, V8

Extreme heavy displacement hulls demand the absolute brutal torque of the Yamaha LF350XCC V8 counter-rotating outboard. The massive 5.3-liter 32-valve block breathes enormous volumes of air, translating digital fly-by-wire inputs into relentless acceleration to launch heavy multi-engine coastal vessels safely. Verifying your twin-engine bracket guarantees this 25 inch counter rotating v8 outboard aligns perfectly without starving the internal water pump in heavy chop.

Eradicate dangerous port-side tracking instability permanently by pairing this specialized left-hand gearcase with your primary starboard V8. You pilot massive twin-engine rigs with absolute single-finger precision via the Digital Electronic Control without fighting stiff physical cables. Yamaha casts the massive 365 kg lower unit using specialized anti-corrosion marine aluminum alloys. This structural barrier stops severe galvanic decay when repowering premium offshore skiffs for continuous saltwater tournament use.

Key Features of Yamaha LF350XCC

- 5.3-Liter V8 Block: Delivers brutal low-end torque from a massive 5330cc displacement, lifting extremely heavy fiberglass hulls onto plane instantly.
- Counter-Rotating Gearcase: Cancels the massive lateral thrust of a starboard engine, keeping twin-engine performance hulls tracking perfectly straight underway.
- 25-Inch Extra-Long Shaft: Drops the propeller deeply below high offshore transoms, maintaining solid forward thrust and preventing water pump starvation.
- Digital Electronic Control (DEC): Translates hand movements into instant electronic commands, eliminating mechanical cable slop during precise marina maneuvering.
- 50-Amp Charging Alternator: Outputs massive charging power, keeping demanding radar systems and heavy-duty livewell pumps fully powered offshore.
- 1.73:1 Heavy-Duty Gearcase: Spins aggressive high-pitch propellers efficiently, translating massive V8 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 LF350XCC

This advanced 25-inch V8 acts strictly as a high-end fly-by-wire power plant designed for the port side of dual-engine applications requiring immense torque. Substituting a V6 model sacrifices critical displacement entirely. Upgrading your digital throttle syncing network is mandatory for smooth 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 350-horsepower drive-by-wire V8 is engineered strictly for ultra-heavy offshore vessels, massive luxury pontoons, and large multi-engine catamarans 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 commercial offshore environments where balancing massive V8 thrust requires precise fly-by-wire power without sacrificing absolute 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 separate terms 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.
