Abstract: A flushing assembly of the type used to clean outboard motors by forcing cleaning water through the inlet ports of the outboard motor and comprising a base specifically structured to provide a water inlet in fluid communicating relation to the inlet ports of the motor. The base is structured so as to be capable of being clamped to the motor being cleaned adjacent the inlet ports and further to allow a water supply to be interconnected to the base wherein both the water supply and the adjustment of the base occurs at a location remote from the motor being cleaned so as to facilitate such cleaning when the motor is not readily accessible.
