Re: 1995 9.9 4stroke, oil change
Some 9.9 use a screw on filter others use a oil screen. both can be found on the lower starboard side of the powerhead. if it is filter, then simply unscrew it and replace with new filter. if it is a screen, unthread the cover from oil screen houisng, inspect the screen and o ring for wear, damage, clean screan with solvent, replace damaged screen and or o ring, and install.
