Yes, the top of the water pump where the shaft goes through. All replacement parts are OEM, it just seems like the shaft seal should prevent any water from coming out around the shaft.
Rubber grommet must be installed into the top of the water pump housing at the opening for the driveshaft.I mistakenly left mine off last month while doing a water pump service.Sounds exactly like what happened to me.As 99yam40 mentioned ,always take note of how things were before the change or save old parts during a changeout as a reference.

That's right there is no seal directly on the shaft. the only seal is the O ring between the SS impeller housing and nylon cover. Yes, I looked closely at all the parts and even reinstall old parts and still water from the muffs goes through the pump and out around the shaft. this was done with lower unit off and with muffs attached. It looks like water is bypassing the O ring, is that possible? Thank you....
Can not see water with lower unit installed. But, lots of water shooting out small drain hole so, assumed water leaking from around shaft. I don't think there should be any water coming out of drain hole when motor is running.
He must have been able to remove the lower unit in a nanosecond so as to see water flow from the water pump.
Have you ever watched your motor before while running on muffs?
Thank you for the cutaway picture which clearly shows water flow coming out from around the shaft when engine is running. I’m sorry to say that I’ve never payed any attention as to where the water comes out when running with muffs, that is, until now that I changed the water pump.Here is water flow from the water pump in action.
