Hello All,
I opened up a garage sale 4.5 yesterday to see about changing the impeller. The lower unit came off as per the Seloc manual, as did the water pump cover. When I got to the impeller, I found that 1 vane had broken off and the others were cracked. I also found that the hub of the impeller was badly worn. No key notch left! As well, there was no sign of the key!
Checking for a replacement impeller, I found that there are two part no. listed: 47-89980 and 47089981 (different I.D.). BTW, the motor serial number is 7199681.
Can anyone help me to determine the appropriate Mercury and/or Sierra impeller part number for this motor? The mangled impeller that was in there had 47-89980 molded into thew rubber. As well, a similar number for the right impeller key would be greatly appreciated.
Does this kind of damage sound normal, or should I be looking more closely for damage at the drive shaft where the key sits?
Thank you in advance for any help with this,
Mitch
