3 Mounting the Outboard Motor
Select an outboard with proper shaft length according to the transom height of your
boat. The top of the propeller should be 100mm to 150mm below the water.
The outboard should be mounted on the centerline of your boat. If the boat shape is
asymmetric, please consult your dealer for proper solution.
3.1 Position of Mounting
The mounting height of the outboard affects the running speed seriously. When the
mounting height is too high, cavitation may occur, which may lead to speed slow-
down, energy waste, and propeller damage. When the mounting height is too low, the
water resistance will reduce both travelling speed and performance of the outboard.
In general, the optimal mounting height is affected by the specific conditions of a
boat. In order to get the optimal mounting height, it’s suggested to test running by
mounting the outboard at different heights. Please consult your dealer for more help.
