V8 60-Degree DOHC 32-Value - The 5.3L V8 configuration is designed to easily produce prop shaft horsepower, with less stress and strain on internal engine components than small displacement, high-output outboards. Four oversized valves per cylinder increase breathing efficiency and contribute significantly to this engine's power and torque.

Multi-Point Electronic Fuel Injection - Seven different sensors constantly measure vital atmospheric conditions and engine functions to give the Engine Control Module (ECM) the information needed to precisely and instantly adjust the fuel/air mixture for optimum performance and economy.

Variable Camshaft Timing - This system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid- rpm ranges. This gives the engine substantially greater torque between 2000 ~ 3500 RPM to plane large offshore boats with authority.

Single Electronic Throttle Control Valve - All air entering the engine is routed through a single 81mm intake that is controlled by the ECM to ensure the precise amount of air necessary for any given condition. This helps maintain optimum power and efficiency.

Dual In-Bank Exhaust with Power Surge Chambers - Yamaha's exclusive In-Bank exhaust means it exits through the center of the engine between the "V" cylinders, rather than on the exterior side, to allow for a more compact shape. The engine also features dual exhaust with Power Surge Chambers, which help the engine more easily purge the exhaust for greater combustion efficiency and power.

Individual Pulse-Tuned Long Intake Tracks - Air enters each cylinder through individual long intake tracks, which are 'pulse-tuned' to provide air at the precise volume and timing for maximum density and power. The result is more low end and mid-range power and torque.

Saltwater Series XL Propellers - In order to harness the power and torque of Yamaha's V8 5.3L four stroke outboard, Yamaha designed special Saltwater Series XL propellers specifically to move large, heavy offshore boats. With larger diameter and 21% more blade surface area than our Saltwater Series II propellers, they help enable these outboards to deliver up to 45% more thrust than 250hp-class outboards.

Enhanced Lower Unit Bearings - An engine with as much power and torque needs lower unit bearings and bearing surfaces that stand up to the test. Yamaha has not only changed the type of bearings and/or increased their site, but also hardened the surfaces on which they ride, for increased reliability.
