The OptiMax 250XS has redefined the term "Performance outboard." Though the world's fastest low emission two-stroke outboard has set world straightaway speed records, it is better known for its durability and fuel economy than it's flat out speed.

A dampener ensures smooth running throughout the engine operating range. New pistons feature an updated profile and composite coating for improved wear life.
