I am putting in a new water pump kit on<br />my 1978-1980 Mercury 20 hp. But the new <br />kit has 1 fiber washer and 2 rubber washers <br />that I did not see when I took the old<br />one apart. and they are all too small to <br />fit on the shaft. I do not see anywhere<br />that they might go. Can anyone tell me <br />where they are to go. The manual I am <br />using does not them in the book.<br />The kit is from Sierra Part # 18-3448
