2 Stroke 30Hp Long Shaft Outboard Engine Boat Motor 30 HP outboard motor displacement is smaller, it easier for maintenance, will give you performance and reliability for your long days of boating. In many countries (especially for the developing areas) of the world where outboard demand is primarily for commercial uses, the water quality, weather and climate variance and long hours of continuous use make for a very harsh use environment. 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.
