    " Easy there sparky [img][/img].. stephen, sparky has it right, I'm just going to add my two cents. The impeller on most outboards is going to be located over the driveshaft, just above where the driveshaft enters the lower unit. The driveshaft is allways spinning when the engine is running, so the engine allways has a supply of cool water. There is also going to be some type of tube above the impeller that will carry water up to the powerhead.
