1979 228 Mercruiser. Alpha 1 lower unit / MC1 upper.
I replaced the water pump on my outdrive and re-assembled and did a pressure test. It leaks down to about 1 lb. over an hours time. I have done the soapy water test on the drain and vent plugs but not sure how to proceed. I did install the quad seal with perfect seal. How do you get at the other seal areas? Do you flip the drive so the yoke is pointing up and then put soapy water in there? ditto with propellor shaft seal?
Should I split the upper and lower at this point?
help appreciated.
