Yamaha F350 world's cleanest outboard
Yamaha said its new F350 outboard continues to set international marine benchmarks with the world's first production 350hp four-stroke V8 production engine now acknowledged as the world's cleanest outboardBased on emission criteria utilised by the star classification system in Australia and the USA, Yamaha said the 2008 emission results for all outboard manufacturers indicate that its F350 is the first outboard to rate below 10 grams of combined nitrous oxide (NOX) and hydrocarbons (HC) per kilowatt of power, per hour (g/kW-h) of operation.
Yamaha said its engineers have raised the standard for all other manufacturers to follow with the F350 achieving a super low 9.171g/kW-h for NOX and HC combined.
Previously dominated by smaller displacement four-stroke engines, Yamaha said the title of the cleanest outboard now belongs to the largest with the 5.3lt F350 leading the world on power and emissions.
The F350 is not the only Yamaha outboard to boast ultra-low emission performance with the big displacement four-stroke F150 engine also shining, said the manufacturer. This 2.6lt four-cylinder F150 outboard holds two spots in the top five lowest-emission EPA data while the F115 four-stroke ranks twice in the top 10 giving Yamaha the majority rule in the clean outboard line-up for 2008, said the company.
Yamaha said the F350 hit the market in 2007 with a long list of technological advancements including multi-point fuel injection, variable camshaft timing, single electronic throttle-control valve and dual in-bank exhaust with power surge chambers.
Engineering a big block V8 into a streamlined and sophisticated marine propulsion package demanded perfection from all corners of the Yamaha development stable, said the company. Every ounce of knowledge gathered over the last four decades of outboard manufacturing was then invested into building the F350, said Yamaha.
The F350's ultra-clean bill of performance has been passed by the ultra-stringent US Environmental Protection Agency, said Yamaha, and with large capacity outboards under the constant scrutiny of emission regulatory authorities, it said the new F350 stands proud as testament to the skill and environmental commitment of its engineers for cleaner and greener boating.
Yamaha also said it will extend the warranty to three years on two-stroke and four years on four-stroke provided the engine is serviced by an authorised Yamaha dealer.
