Powerhead Specifications

• Engine Type: 4-Stroke, 60-degree V6, 24-Valve DOHC

• Displacement: 4,169 cc (4.2 Liters)

• Bore x Stroke: 96.0 mm x 96.0 mm

• Full Throttle Operating Range: 5,000 – 6,000 RPM

• Fuel Induction: Electronic Fuel Injection (EFI)

• Plasma-Fused Sleeveless Cylinders: The cylinder walls are created using a specialized fusion process that results in a surface 60% harder than steel. This replaces traditional steel sleeves, significantly reducing weight while expanding displacement and improving heat dissipation. 
• Variable Camshaft Timing (VCT): This system alters the camshaft timing based on engine RPM. It maximizes low-end torque for a faster hole shot and quick planing, while optimizing the mid-range fuel mix. 
• In-Bank Exhaust System: Yamaha integrates the exhaust manifold directly into the cylinder head casting. This slims down the overall dimensions of the powerhead and reduces the engine's physical weight profile.
