This motor is new to me and seems to have been well maintained and starts/runs great. After use and flushing the motor (I live in FL) some oil leaks from a tiny hole on the bottom side of the cavitation plate above the prop . It looks murky/frothy with some water mixed in. It drips on the prop then stops after a while. The little hole it leaks from pees water when I flush the motor. Is that supposed to be there? I can't find any reference to it in the manual I have. The lower unit oil seems to be ok.
