18 Operation EMU26901 Installation CAUTION: ECM00110 Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat, or accessories such as transom ladders or depth finder transducers) can create airborne water spray while the boat is cruising. Severe engine damage may result if the motor is operated conti[...]

Operation 19 motor greatly affects the water resistance. If the mounting height is too high, cavitation tends to occur, thus reducing the propulsion; and if the propeller tips cut the air, the engine speed will rise abnormally and cause the en- gine to overheat. If the mounting height is too low, the water resistance will increase and thereby reduc[...]
