New cleaning system for cooling water line in outboard engine was developed, and the trial equipment was produced. For this system, cleaning fluid which mixed the scallop powder and the compressed air into the water was used. The experiments for cleaning the acrylic resin tubes which simplified cooling water line of the outboard engine and the actual outboard engine were conducted, in order to evaluate the removal effect of the fouling. The results show that the removal effect was the best in scallop concentration 5% in the experiment using the acrylic resin tubes; The removal of the fouling was confirmed, when cleaning fluid of the flow rate 30 L/min, the concentration of the scallop powder 10%, running time 20 min, and the pressure of compressed air 0.08 MPa was used, in the experiment using actual outboard engine.
