Yamaha LXF450ESA2 450HP XTO Counter-Rotation 35″ Motor

Description

The Yamaha LXF450ESA2 is a 450hp counter rotation outboard designed with a 35-inch ultra-long shaft for multi-engine offshore boats. This 5.6-liter 60-degree V8 block displaces 5559 cc and tips the scales at a dry weight of 1010 lbs, engineering a perfect balance of structural rigidity and raw displacement. Built explicitly for towering 35-inch transoms, the ultra-long shaft ensures that the massive quad-blade propellers stay buried in clean water when driving through steep head seas.

Running hard within its 5000 to 6000 RPM range is how this offshore engine sustains incredible cruising speeds across long tournament distances. The heavy-duty 1.79:1 gear ratio converts pure combustion forces into a flat torque curve, ensuring heavy boats pop onto plane without burying the stern. This Japanese-built masterpiece leverages advanced block harmonics to eliminate the typical low-frequency rumble associated with running large-displacement powerheads in demanding saltwater conditions.

Technical Specifications of Yamaha LXF450ESA2

• High-pressure direct fuel injection atomizes fuel at 2900 PSI to squeeze every ounce of energy out of every drop.
• A heavy-duty 102 gross amp alternator generates massive charging power to keep complex house battery banks fully topped off.
• The fully integrated electric steering mechanism replaces complex hydraulic lines with instant digital response at the steering wheel.
• The proprietary TotalTilt system simplifies trailing and shallow-water operation by tilting the massive lower unit completely out of harm.
• An extensive 7.8-liter oil sump ensures optimal thermal dissipation and continuous lubrication during hard wide-open throttle runs.
• The specialized counter-rotation gearcase balances out propeller torque to maintain tracking on multi-engine express cruisers.

Sleeveless V8 Powerhead Block

Plasma fusion technology creates micro-textured cylinder walls in this sleeveless 32-valve double overhead camshaft V8 to improve thermal efficiency. This cutting-edge process shaves critical pounds off the powerhead while vastly improving heat transfer under severe offshore operating conditions.

High Pressure Fuel Delivery

Direct fuel induction sprays gasoline straight into the cylinders under high pressure for clean combustion on 89 octane fuel. This meticulous delivery guarantees instant throttle response and crisp acceleration when timing massive ocean rollers.

Heavy Duty Lower Unit

Oversized internal gears and a highly hydrodynamic gearcase profile minimize underwater drag at high cruising speeds. This structural configuration mitigates lower-unit gear chatter and ensures smooth power transmission to the hub.

Digital Fly By Wire

Digital electronic control systems integrate directly with the steering setup to automate multi-engine tracking and trim adjustments. This seamless network allows captains to execute precise docking maneuvers with a single intuitive joystick control.

Five Year Protection Plan

A factory-backed five-year limited pleasure warranty guarantees peace of mind when running deep into blue water fishing zones. This comprehensive protection confirms the absolute long-term durability of Yamaha’s heaviest structural offshore platform.

Offshore Hull Match

Large offshore center consoles, catamarans, and fiberglass express cruisers from 30 to 45 feet are the target vessel application for this 35-inch motor. The extended length provides perfect prop immersion, preventing ventilation when climbing over steep swells.

Cowling And Oil Access

Fast access to vital checking points is provided by a multi-piece outer cowling system that saves hours during routine servicing. Changing oil is a clean affair thanks to a well-positioned drain plug that keeps mess out of your transom. Pro Tip from the Shop: Pull the gear lube plugs at the dock and use the lower unit pressure system to push fresh oil from the bottom up, ensuring zero air pockets form in your heavy-duty gears.
