Re: 77 25hp evinrude lower

marineengine.com or boats.net have diagrams of your motor...your lower unit comes apart at the upper and lower shell seam...with the lower unit off the motor, you can invert the lower unit..split the seam...and it all comes apart pretty simply...the propshaft seals..howerver you can w/o scratching the bearing head or propshaft..put back in by tapping in with a piece or pvc pipe or socket...I believe you're supposed to replace the bearing head w/seals as a unit...probably a slap hammer to remove that upper d/s bearing....which manual do you have?
