Shift-cam positions on 1975 850

[Kensandyeggo]

Had lower unit apart to replace impeller. Shift shaft came out and cam # 76039 fell in. Fished it out and don't know which way it goes on, as with lobe up, one side is contoured and one side is flat. Couldn't find a diagram or video showing the correct orientation. The part number is stamped on one side and I need to know which way this side faces when reinstalling it on the shaft, to the front or the rear of the motor.

Problem #2. I took photos of the orientation of the cam # 76039 and plastic piece on the other end of the shift shaft so I would know how to position them on the splines relative to each other, but alas, this photo disappeared somehow. If I had it, this would solve the first problem also.

Motor serial number is 4101471 and thanks. for any help. This is my first post as a new member.

Holy cow! What more could I ask for? Thank you so much. Will get to it as soon as the temp gets out of the 30's and post how it went.

The shift shaft bushing has seals in it (Page 1) and you might as well replace it before you re-assemble.Also it's a good idea to follow these instructions:
