Given the high technology of the outboard marine engine and the fact that basic design and manufacturing process of these engines are exclusively restricted to limited engines in commercial and navy vessels, the MIO decided to complete the technical design and product process of outboard engines taking advantage of capabilities of the industries. Technical specification: The REV-200 is the first marine outboard engine that has been designed and produced by Iranian engineers. Good performance, fast operation, as well as complete familiarity with the base engine in the field of after sales and supplying engine part are from among the unique features of this outboard engine. Undoubtedly, achieving the design and manufacturing technology of outboard marine engine up to 200 hp is a suitable field to develop design and production process to a wide range of power to the related industry requirement.
