My 1993 Yamaha 15 HP 2 stroke engine does not pass water through the "pisser" with muffs on and engine running. I found that the woodruff key was completely gone from the system when I removed the lower drive assy. The impeller looked fine although the fins were a litle curved, although it seemed to fit tightly in the pump cylinder. While loose I found the system was not clogged through the "pisser". When I put it back together, no output from the water pump. I tried both with muffs on and in a bucket. Any suggestions? TIA.
