A position control system for a marine propulsion device senses an undesirable operating condition in the propulsion engine, such as low cooling water pressure at high speed or high engine temperature, to automatically lower the drive unit to a position in which the undesirable operating condition is likely to be alleviated. The system may include a logic timer circuit which will lower the drive unit for a short period of time, hold it in that position if the undesirable condition has been eliminated, or lower the drive unit further if the undesirable operating condition remains. The position control system may be incorporated into a conventional lift system, particularly a lift system used with a transom extension mounting assembly.
