Note: Keep the bow higher than the stern every time the boat
is lifted. Do not lift the stern to change a propeller. Doing so
can cause water to enter the engine. Engine failure is possible
if water enters the engine cylinders. This water can cause
hydrolock and bend the piston rods. Even a small amount of
water can cause rust or other damage.
