A water cooled four-cycle outboard motor having an improved flushing system that permits flushing of the cooling system without removal of even the protective cowling and which permits flushing to be accomplished with a minimum of water usage. The flushing connection is coupled with a tell tale connection to provide a simple, but highly effective construction. In addition, the system effectively cools the engine and a temperature sensor is positioned in an area where it will be protected from overheating.
