1955 Mercury Mark 5 s/n 764886

I am trying to replace the water pump impeller on my Mark 5 and I do not have any maintenance manual information.

It appears that the neutral shift cable needs to be disconnected to allow the lower unit to be removed and reveal the water pump impeller.
How do you disconnect the shift cable?
Is there some other procedure that I am not aware of?
Thanks,
Rex Perry
