Lift motor seals?

I’ve searched both here and more broadly via google but haven’t come up with any specific info on the shaft seal and motor end bell o-ring. When I return home from vacation, I’m going to have to tear into my Lift efoil motor to see why it isn’t running properly and I suspect water has made its way inside. I feel like I can probably come up with the dimension for the large end bell/motor body o-ring by measuring once I pull it apart, but I’m not so sure about the shaft seal. Any idea what that that type of seal is called? Has a specific part number ever been found?
