jay, on your boat, just pull off the ends of the heater hose (5/8", black) and literally blow into one side and water will come out the other. There is a shut-off valve (like you'd see for a hose on the side of the house) on the starboard side. The hose coming out of there is the input hose. Then look for the other hose coming back from the bow that is the same size, it will plug in in the back of the motor, access it from the port side.
