When installing a marine gasoline engine, the installation height should be such that the anti-vortex concave panel is located below the stern flat keel. If the installation height is too high, it will cause the propeller to run idly and reduce the efficiency, and may cause the engine to overheat due to lack of cooling water. damage etc. If the installation height is too low, the flight resistance will be increased, the driving power of the engine will be reduced, and the outboard motor should be installed on the base vertical line of the transom.
