Yamaha LXF450ESA 450HP Outboard – 35in Shaft, Counter Rotation, XTO

Description

Towering 35-inch multi-engine transoms demand the extreme reach of the counter-rotating Yamaha LXF450ESA to maintain absolute propeller bite. The upgraded 450-horsepower V8 utilizes advanced direct fuel injection up to 2900 PSI, forcing explosive acceleration when pushing heavy offshore catamarans through steep ocean swells. Verifying your twin-engine bracket guarantees this 35 inch ultra long shaft counter rotating outboard aligns securely without starving the internal cooling intakes.

Eliminate dangerous port-side tracking instability permanently by pairing this specialized left-hand gearcase with your primary starboard engine. You pilot massive commercial vessels safely across treacherous coastal inlets while the built-in Digital Electric Steering system executes flawless directional changes. Engineers cast the 458 kg ultra-long lower unit using specialized anti-corrosion marine aluminum alloys. This structural barrier stops galvanic decay completely when repowering large offshore vessels for daily saltwater exposure.

Key Features of Yamaha LXF450ESA

• 35-Inch Ultra-Long Shaft: Reaches incredibly deep beneath towering offshore transoms, preventing water pump starvation in heavy ocean chop.
• Counter-Rotating Gearcase: Cancels the massive lateral thrust of a starboard engine, keeping twin-engine performance hulls tracking perfectly straight underway.
• 5.6-Liter V8 Block: Delivers brutal low-end torque from a massive 5559cc displacement, lifting extremely heavy fiberglass hulls onto plane instantly.
• Direct Fuel Injection: Sprays fuel directly into the combustion chamber at 2900 PSI, maximizing power output and overall fuel efficiency.
• Integrated Digital Electric Steering (DES): Eliminates messy external hydraulic cylinders completely, delivering sports-car-like handling and zero steering fatigue during long runs.
• 102-Amp Gross Alternator: Generates massive electrical current continuously, keeping deep cycle house batteries fully charged for heavy-duty marine electronics.
• TotalTilt System: Lifts the engine completely out of the water quickly with a double tap of the trim button, preventing marine growth accumulation.
• Variable Camshaft Timing (VCT): Shifts intake timing dynamically to boost low-end and midrange torque, maximizing acceleration for heavy offshore boats.
• 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 LXF450ESA

This advanced 35-inch V8 acts strictly as a high-end fly-by-wire power plant designed for the port side of dual-engine applications demanding extreme shaft lengths. Substituting a mechanical control model sacrifices electronic shifting entirely. Upgrading your digital throttle syncing network is mandatory for smooth engine communication.

• Verify your twin-engine transom bracket accommodates a 35-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 450-horsepower drive-by-wire V8 is engineered strictly for extra-deep transom offshore vessels, massive luxury pontoons, and large multi-engine catamarans demanding a 35-inch shaft. Operating as the port-side drive equipped with integrated DES, it actively cancels starboard propeller torque to keep the vessel tracking perfectly straight at high cruising speeds. It thrives in commercial offshore environments where balancing massive thrust requires precise fly-by-wire power without sacrificing absolute tracking stability.

Warranty, Support and Maintenance

Authorized recreational operation receives a 5-Year Pleasure 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.
