Re: 1963 Evinrude 40 HP Electric Shift water and oil mixing
I got my pressure tester on Ebay for about $30. It screws into the oil drain plug hole and you can pump it up with a bicycle pump to about 10psi. Should hold at this pressure for about 20 minutes. Once pressure is applied, if it is leaking, spray some dish soap on the prop shaft, oil vent bolt, little Phillips head screw to see if they are leaking. If these are not the source of the leak, then it is probably the drive shaft seal or shift rod seal.
