I got an Evinrude 200 hp ('93, Serial No Q02614230). Last week end while running the motor on a flushing device I notice a lot of water coming out on the lower unit where the unit is bewing bolted on. The water pump indicater stream was barely coming out sometime water was just tripping out. A mechanic told me that I shouldn't worry about water coming out on the lower unit, but I am worried about low water pressure and water just dripping out.<br /><br />Any advice appreciated. How difficult would it be to cleam and replace water pump / impeller?
