F350

Yamaha V8 Offshore Range - Description

Deliberately designed to withstand the harsh demands of a marine environment, the V8 F350 features:

Wave-Crushing Power
The world’s first 5.3-liter four stroke outboard, the F350 provides unparalleled displacement and up to 45% more thrust than 250hp-class outboards. When it launched in 2007, its industry-rocking 60° DOHC, and 32-valve, 5.3-liter design redefined offshore power. It’s taken almost five years for the competition to even remotely catch up.

Deep-Water Durability
To handle the incredible power of the F350, its Ultra-Tough Gearcase features hardened gears and high-strength, oversized bearings and bearing surfaces. It also features strong, forged motor mounts and an oversized bracket specifically designed to harness its massive power and thrust while minimizing vibration and noise.

Corrosion Resistance
Saltwater wreaks havoc on metal engine components. Our Ultimate Corrosion Protection System (UCP II™) places sacrificial anodes throughout the powerhead, mid-section and lower unit, diverting corrosion away from vital engine components.

Fuel Efficient Design
Burning just 31.7 gal/hr @ 6000 RPM (depending on application), the F350 offers incredible fuel efficiency for such an unbelievable Ultra Low Emission amount of power. This comes in handy when you’re putting hundreds of miles on in a day.

Intuitive Control
Harness the power of the V8 F350 with the Helm Master^® fully integrated boat control system. It supports twin-, triple- and quad-outboard configurations, and makes docking and maneuvering a large offshore boat—even those exceeding 40 feet—very intuitive.
