WORLD'S MOST POWERFUL LOW-EMISSIONS 2-STROKE
Mercury Racing has a reputation for exceeding consumer expectations in product quality and performance. The all-new OptiMax 300XS outboard continues our heritage of delivering more power and performance than competitors with the same horsepower rating. The heart of the 300XS “Stroker” is a 3.2 Liter V-6 powerhead with a stroked and precision-balanced crankshaft for maximum power and performance. The unique reed shape increases airflow for improved engine throttle response. The 300XS top cowl features bold
new graphics and a power designation that can’t be missed. Using an acoustically-tuned
foam cowl liner and attenuator for the direct fuel injection air compressor and an advanced exhaust system, results in a dramatic reduction in engine sound at idle through mid-range operating RPM. “Highest in Customer Satisfaction with Two-Stroke Outboard Engines Two Years in a Row!” Mercury received the highest numerical score for DI twostroke engines (tied in 2007) in the proprietary J.D. Power and Associates 2006-2007 U.S. Marine Engine Competitive Information Study. SM 2007 study based on 8,238 responses, measuring 3 DI two-stroke engine brands and owner opinions of 2005 and 2006 model year boats registered June 2005-May 2006. Proprietary study results are based on experiences and perceptions of owners surveyed September-October 2006. Your experiences may vary. jdpower.com
In recent tests,conducted by Mercury Racing and observed by an independent agency,the OptiMax 250XS outperformed the Yamaha® 300 HPDI® low-emissions outboard in acceleration,top-speed and fuel economy. The introduction of the OptiMax 300XS sets a new standard in DFI outboard performance. We look forward to going head-to-head with competitor outboards badged with like horsepower ratings.
