This is the two stroke outboard motor series developed mainly for commercial use such as on fishing and passenger vessels. This series suits harsh conditions that include everyday use and situations involving long hours of continuous operation.
Enhanced strength and durability in locations such as roller bearings, crankshaft and cylinder block, as well as an improved water pump that ensures plenty of cooling effect, combine to deliver substantial improvements in durability and reliability. Models fueled by kerosene are also available in addition to gasoline engines.
