For the record, I HATE ALL WOODRUFF KEYS! There, it's off my chest. I have prevailed over this tiny chunk of metal by using brute force! My water pump impeller was fine but the plastic housing had some interior glazing and slight melting so I will be replacing it. I remember the day that I ran the motor before the barrel filled completely - never again! Make sure you have enough water to cover the lower unit COMPLETELY or use positive pressure muffs to achieve the same effect.
The water pump impeller change was easy. Except for the key removal. Next time I will do it at our shop so I have access to a compressed air rotary grinder to cut that sucker out. I won't wait another 440 hours to change it either. I see now the advantage in changing every 300 is to prevent accumulation of corrosion on metal parts. Salt away seems to have done a great job on mine EXCEPT for the *&%$@# woodruff key. I used plumber's silicone to make the o-rings sticky so they would stay in place for assembly.
Any other pointers before I complete ass'y?
