Hi all, I have a 1973 Mercury 850 motor serial number 3744807 with a pitted drive shaft in the seal area. I'm looking for the exact specs on the drive shaft seal area OD and length of seal area above and below the water pump and at the upper crank seal area. I checked out a speedi sleeve but I am unable to get the width I need. Can anyone help.
