Yamaha V-8 outboard wins 'Best of Year' award from Motor Boating

Yamaha V-8 outboard wins 'Best of Year' award from Motor Boating

Yamaha Marine Group has announced that its F350, the industry's first V8 5.3-liter four-stroke outboard, has won a "Best of the Year" award for 2007 from Motor Boating Magazine.

Motor Boating's "Best of the Year" awards celebrate innovations and exceptional events that take place during each calendar year. This year, the magazine presented 11 awards spanning several categories including: engines, electronics, boats, and most heroic boater.

"Yamaha really shattered the technology barriers when they unveiled the industry's first V8," said Jeanne Craig, executive editor, Motor Boating. "We are pleased to present Yamaha with this award and applaud the company's bold innovation and ability to take outboards to the next level in terms of power and thrust."

Launched at the 2007 Miami International Boat Show, the F350 produces a 350 prop-shaft rated horsepower, and is designed to provide massive thrust for the heaviest off-shore outboard-powered boats. At the same time, displacement means the engine makes 350 horsepower without the strain and internal pressures found in high-output, small displacement engines.

Along with being more resistant than before to the potential for water intrusion, the new motor also uses a number of new technologies, including: ionic combustion sensors that constantly monitor combustion conditions and adjust spark timing; a dimpled outer cylinder sleeve to reduce oil consumption; the new Enhanced Ultimate Corrosion Protection System (UCP-II(TM)) with additional sacrificial anodes; an innovative internal paint process and new-generation head gaskets; and Yamaha's Command Link Digital Electronic Control system with redundant electronic engine control, automatic multi-engine synchronization and electronic throttle and shift.

The company's first V8 outboard powerhead was designed specifically for the marine market and features more than 600 new parts. The design is a 60-degree V8 with 32 valves (four valves per cylinder) and double overhead cams. It uses variable camshaft timing to optimize the engine's torque at low and mid-range rpm. With sequential, multi-point fuel injection, it has eight long intake tracks in the induction system to optimize power. In addition, it features In-Bank Exhaust with Dual Power Surge Chambers, a system that relieves pressure in the exhaust ports.

The F350 was designed from the beginning to power off-shore boats. However, it employs a number of new features designed to even further enhance its off-shore capabilities.

In addition, the outboard uses an "Ultra-Tough" gear case with dual water inlets for improved cooling. Inside the lower unit are hardened gears and enhanced bearings and surfaces for greater off-shore durability. Forged motor mounts and an oversized mounting bracket also add to the F350's portfolio of toughness.
