[QUOTE="roblj65, post: 211656, member: 6354"] Thanks for responding Pappy, I appreciate it. I did replace the shift shaft o-ring, that is not the o-ring I was talking about. The o-ring I was talking about is a little bit smaller in diameter, and about a 1/5th of the thickness. The reason I am thinking that an o-ring goes on the top of the drive shaft, is because there was remnants of one in the grove just below the spline that goes into the power head. Only problem is, that the o-ring that was in the kit is much smaller than the one that came out. Also, the following link https://www.marineengine.com/parts/vintage-evinrude-johnson/278779/catalog.html?https://www.marineengine.com/parts/vintage-evinrude-johnson/278779/27877900001.htm has a parts diagram for the lower unit (1966 18hp Evinrude Fastwin) page 12 reference # 11 that shows a o-ring that goes on drive shaft, but does not show where it goes. Everything else has been replaced, (shift shaft o-ring, drive shaft seal, Gear case Head o-ring, and propeller shaft seal) [/QUOTE]
