plastic wedge on johnson water pump

[kenskat1]

I have a 1990 johnson 90. I am replacing the water pump, there was two plastic wedges that came with the kit. I tryed to get the white one to work could not get it to line up so I used the smaller black one. Need to know what the differance is. Is the black on ok to use. a white came out of the old pump.

Compare the key way of your old impellor to that of the new impellor,that should tell you what key touse. Were there instructions in the kit you bought?

No! I bought it from iboats, Just a diagram showing where to place a o ring just below the key slot.

they are different sizes, they package them for several different motors. use the one that fits.

When using the black key,does the impellor lock on to the drive shaft?

Yes it does, but only turn the shaft in the clockwise direction.

Use the drive key that matches the one you took off.
