Those motors have an inherent problem with grease leakage into the pump. The grease seal is pressed into the brass bushing. It is an Oilite bushing, meaning it is porous–like a sponge. So the grease liquifies and goes through the porosity, right past the seal. I modify all mine by cutting the bushing back 1/4" and installing a seal right into the housing instead of into the bushing. There is an OMC seal that fits.

The seal on the vertical drive shaft is difficult to remove. There is a screw-in bushing that holds it together and most of them won’t come out without a fight. I just leave it alone and change the grease as it leaks.
