I have no tell tale from the pee hole when motor running. Water pump is about 4 years old, but not many hours on the motor after new pump installed. If I do find the water pump is the culprit do I have to disconnect the shift linkage under the cowling and also should I place the motor in forward or reverse when doing this? If I dont twist the shift rod after I drop the lower unit then I should be alright upon re-assembly? Thank you for your help.
