i have a 48 hp johnson and the tilt and trim was leaking out of the top shaft seal and i rebuilt the unit and bled it and it works fine but still leaks out of the top shaft seal . when i replaced the seal in the cylinder end cap (the cap with the spanner wrench holes ) directly under the seal is a groove that is filled with some waxy type stuff and alot of that was missing could this be my problem ?? any info would be greatly appreciated
