The Mercury 115 OptiMax is a direct-fuel-injected 2-stroke outboard known for strong acceleration, good fuel economy, and lighter weight compared with some 4-strokes. Proper maintenance is important, especially for the air compressor, fuel system, spark plugs, oil system, and cooling components.

Because OptiMax engines use direct fuel injection and an air-assisted fuel system, it is important to choose parts that match your exact horsepower, model year, and serial number. Routine service can help prevent hard starting, poor idle quality, fuel-delivery issues, compressor problems, overheating, and reduced performance under load.
