OptiMax 300XS
The World's Most Powerful 2-Stroke Low Emissions Outboard.
Mercury Racing is all about passion for perfection and the pursuit of peak performance. We have a reputation of exceeding consumer expectations in product quality and performance - something we've carried forward from the late Carl Kiekhaefer, Mercury Racing president Fred Kiekhaefer's father and founder of Mercury Marine. 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 new 300XS "Stroker" is a 3.2 Liter V-6 powerhead featuring a stroked and precision-balanced crankshaft for maximum power and performance. A dampener ensures smooth running throughout the engine operating range. New pistons feature an updated profile and a composite coating for improved wear life. Piston ring life is doubled thanks to a composite chrome coating.
The exhaust port, combustion chamber and fuel induction designs are direct descendants from our Formula 1 tunnel boat race engine. Airflow through the reed block fuel induction system is enhanced due an enhanced air box design along with thinner reed material and the unique reed shape developed for Formula 1 racing.
As with the complete line of Mercury Racing OptiMax XS outboards, the 300XS comes with a heavy-duty direct fuel injection air compressor featuring robust maxi-coated mounting brackets and hardware for enhanced compressor durability and reliability.
Customer Satisfaction
Mercury OptiMax – the marine industry's leading DI two-stroke outboard – was recognized as "Highest in Customer Satisfaction With Two-Stroke Outboard Engines." OptiMax engines are made in Fond du Lac, Wis., home of Mercury Marine.
Mercury Marine is the only marine engine manufacturer to receive this prestigious award three years in a row.
The 2008 study found that OptiMax ranked highest for overall satisfaction among two-stroke outboard engine owners. On average, Mercury OptiMax engine owners also reported fewer problems per 100 boats than the competition. In terms of fuel economy, owners again gave the OptiMax top marks.
