Mercury OptiMax Outboards 250 XS

• Injects the air/fuel mixture into the combustion chamber at 95 psi (15 psi higher fuel/air differential than the standard DFI or OptiMax product) for enhanced high rpm quality.
• Mercury Racing custom designed pistons and o-ring cylinder heads, with special combustion chambers.
• A unique two-stage direct-injection system atomises fuel into small, uniform particles, resulting with a complete and instantaneous combustion.
• High performance cylinder liners, featuring race-derived transfer and exhaust ports with hand ground boost ports, increase power and performance.
• PCM 03 microprocessor provides maximum power and fuel economy.
• Electronic multipoint lubrication system delivers precise amounts of oil where and when it's needed.
• High performance rubber coated reed blocks cushion five-petal, single-stage carbon fibre reeds for enhanced reed life without sacrificing performance.
• Solid engine mounts improve engine response and overall boat performance at higher speeds.
• Torque Master and Fleet Master gearcases feature dual water pick-ups (mounted on the nose of the torpedo and strut) for improved cooling, enhancing engine durability and overall performance.
