A device for introducing liquid into the cooling system of boat motors having drive units with skags, cavitation plates, propellers, and water intakes, comprises a preferably contoured container adapted to fit about the lower portion of the drive unit and to extend above the cooling system water intake. Such a container fits closely about the drive unit below the water intake but loosely about the water intake and above, so that, when the container is in place about the drive unit, liquid will be sucked into the water passages of the motor. The device may be used in connection with winterizing the motor, and in such case the container will hold a sufficient amount of antifreeze to, when mixed with the water in the cooling system, adequately protect the motor against freezing. The motor is run long enough to distribute the antifreeze through the cooling system. For checking motor operation, with the boat out of water, cool water is run into the container and motor operation is continued as long as required.
