Serial # 2B089126. Does this motor get the large thick o-ring (the one that seats on top of the pump housing with the little special tool) that goes down the drive shaft after the pump housing is bolted up?

The "o-ring" in question is called a centrifugal slinger.
Cannot say with absolute certainty yours does not but my 150 Opti does not. If you are the only who has ever had the lower unit off and there wasn't one from the factory, I'd say yours doesn't use it. Maybe Don will confirm for certain based on your serial number.

I am actually the 2nd owner. Motor has only 55 hrs and the original pump was supposedly replaced at 39 hrs. I just installed a smart craft and noticed idle pressure was low so I pulled the lower (gasket below impeller plate was torn) and replaced impeller, housing, 2 gaskets, impeller plate, ect. It had the slinger gasket installed so I went ahead and reinstalled it back.Originally Posted by SilverFox579

I have had the boat out since rebuilding pump. I am getting anywhere between 1.7-1.9 psi at idle and somewhat on the lower spectrum at WOT. I was expecting pressure around 2+ psi. Will having that "slinger" installed cause any problems, reduced pressure, ect? Should I drop it back down and remove?
It will not "hurt" anything... it's just not needed.
Idle water pressure for this engine model is 1-3 psi.
Good call doing the water pump- in a fishing application, it should be considered ANNUAL (every year) Maintenance.
