Yamaha LXF450ESA 450HP V8 XTO Counter-Rotation 35″

Description

The Yamaha LXF450ESA is a 450hp counter rotation outboard designed with a 35-inch ultra-long shaft for multi-engine offshore boats. This 5.6-liter V8 platform handles extreme high-seas operation by distributing its massive 5559 cc displacement over a heavy dry weight of 1010 lbs to maximize rigidity. Crafted explicitly for towering deep-V sterns, the 35-inch shaft length ensures complete propeller immersion and continuous bite across large catamarans and express cruisers navigating open ocean waters.

Sustaining high-speed cruising across extreme tournament distances is easy when running this heavy-duty powerhead within its 5000 to 6000 RPM threshold. The optimized 1.79:1 gear ratio translates massive internal combustion pressures into a sweeping torque curve to lift wide hulls on plane rapidly. Backed by proven Japanese engineering excellence, the propulsion platform provides absolute mechanical consistency for captains operating far beyond standard coastal cell phone service ranges.

Technical Specifications of Yamaha LXF450ESA

• High-pressure direct fuel injection pushes gasoline at 2900 PSI for complete combustion and clean power delivery.
• A robust 102-amp gross alternator easily satisfies the heavy electricity demands of modern multi-display helms.
• Integrated electric power steering removes traditional hydraulic lines to streamline rigging and responsive vessel tracking.
• The handy TotalTilt feature makes trimming easy with a built-in automatic tilt limiter for shallow waters.
• An extensive 7.8-liter oil reservoir ensures components stay thoroughly lubricated during long wide-open throttle runs.
• The counter-rotation lower unit ensures reversed propeller spin for balanced tracking on dual or quad engine configurations.

Sleeveless Cylinder Wall Tech

Plasma fusion metallurgy treats the internal cylinder walls of this 32-valve double overhead camshaft V8 to optimize overall thermal efficiency. This advanced build path cuts unnecessary pounds from the powerhead block while drastically accelerating thermal dissipation under severe high-load operations.

Three Stage DFI System

Direct fuel induction pushes fuel straight into the heart of each cylinder at pressures topping 2900 PSI for complete combustion. This automated network produces crisp throttle recovery and instant starting capability when navigating treacherous inlets or heavy head seas.

Hydrodynamic Lower Gear Housing

Oversized drive gears housed inside a hydrodynamic lower unit minimize underwater drag profiles during high-speed cruising maneuvers. This robust engineering dampens heavy gear-shift vibration while maximizing directional tracking on deep-transom multi-engine fiberglass hull configurations.

Integrated Electric Steering System

Integrated electronic steer-by-wire units delete messy external hydraulic lines and valves to provide uncompromised helm response and handling. This digital platform coordinates with a high-capacity 102-amp gross alternator to supply constant power to critical open-water electronics arrays.

Target Vessel Hull Integration

Large offshore center consoles, express cruisers, and catamarans ranging from 30 to over 45 feet provide the perfect match for this outboard. Its 35-inch ultra-long shaft prevents propeller ventilation when ascending massive rollers in rough open-ocean swells.

Rapid Fluid Servicing Access

Unimpeded maintenance access is guaranteed by a multi-piece cowling array that detaches smoothly for immediate dipstick evaluation. Slick drainage pathways isolate waste fluids to allow for quick oil changes right at the marina slips. Pro Tip from the Shop: Connect your freshwater wash hose directly to the upper flushing port after every trip to automatically blast salt crystals out of the cooling jacket without even starting the engine.
