Yamaha LXF450ESA2 450HP XTO Counter-Rotation 35″ Motor

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, combining a rigid V8 design with substantial displacement. Built explicitly for towering 35-inch transoms, the ultra-long shaft is intended to place the lower unit at the appropriate depth when driving through steep head seas.

The 5000 to 6000 RPM operating range should be matched to the boat, load, propeller, and intended use. The 1.79:1 gear ratio should be matched with an appropriate propeller and boat setup. Engine sound and vibration characteristics will vary with installation and operating conditions.

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 during normal marine operation.

High Pressure Fuel Delivery

Direct fuel induction sprays gasoline straight into the cylinders under high pressure for clean combustion on 89 octane fuel. This delivery is designed to support instant throttle response and crisp acceleration during acceleration and normal operation.

Heavy Duty Lower Unit

Oversized internal gears and a hydrodynamic gearcase profile minimize underwater drag at high cruising speeds. This structural configuration mitigates lower-unit gear chatter and helps support 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 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 is designed to support peace of mind when running deep into blue water fishing zones. This comprehensive protection is subject to the terms and conditions provided by Yamaha’s heaviest structural offshore platform.

Cowling And Oil Access

Fast access to vital checking points is provided by a multi-piece outer cowling system that can simplify routine access. Oil-service access is supported by a well-positioned drain plug that keeps mess out of your transom.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
