When the gearcase is filled to the proper level, the gears will act as a pump and move the oil up towards the bearing. If you look closely at a 5.5 horse case for instance, you can see an opening in the casting for the oil to come thru. I don’t have a 25 handy to look at but I’m sure it’s similar.
What year is the motor? Earlier ones had a bushing while later ones had a Torrington needle bearing below the water pump.
