350HP Yamaha outboards

350HP Yamaha outboards is a feat of engineering. It can easily produce 350 hp and provide amazing torque between 2000 and 3500 RPMs because to its huge displacement and cutting-edge valve train. And when you have a huge offshore boat, torque is everything. Owners of 350HP Yamaha outboards  will tell you that nothing else has the power to get you on an aircraft.

Performance & Power for 350HP Yamaha outboards
Big Power: Compared to small displacement, high output outboards, the 5.3-liter V8 architecture is built to readily deliver 350 prop shaft horsepower with less stress and strain on internal engine components. Each cylinder has four larger valves, which improve breathing efficiency and considerably increase the F350C’s power and torque.
Greater torque Individual, long intake air tracks and variable camshaft timing provide the engine much more torque between 2000 and 3500 RPM. This has the authority to plane big offshore boats.

Durability and dependability
dependable and sturdy: For more strength than cast aluminum motor mounts, its robust forged aluminum motor mounts are squeezed in molds. Additionally, to reduce noise and vibration, its bigger mounting bracket has six bolts (two more than our F250).
Most effective corrosion resistance: The Yamaha Ultimate Corrosion Protection System safeguards your outboard whether it is the traditional gray F350C or the brand-new pearlescent white F350C. In order to keep corrosion away from crucial engine components, sacrificial anodes are installed in and around the power head, mid-section, and bottom unit. These are unique alloys, our Phaze FiveTM paint process, and sacrificial anodes. Additionally, a freshwater flushing system aids in post-run cleaning of corrosives.
