I have a single small o-ring in the water pump kit that is 7/16" od about 0.25 id. It is not for the vent or fill screws, I have id'd the gaskets in the kit for them already.

Does it go to the flush screw at the water pump - shift shaft above the bushing seal - I'm not sure.

When I tore my lower unit apart I made sure I placed everything in sequential order. After everything was disassembled - I see another small o-ring that I didn't recall seeing in my tear-down that was about the same size.

A lot of waterpump repair kits fit multiple motors, and have extra parts. Normally you would have several large waterpump base orings left over as well as some extra water pump base and cover gaskets.

What kit did you buy?

You can look up your motor at the crowleymarine.com website and see if it shows you where to put it. Mercruiser Alpha I outdrives can use a universal waterpump kit. They have an oring between the upper and lower gearcases.
