"When filling lower unit oil, oil started coming out of water intake inlet. Is there a overflow valve system for the lower unit oil?
Thanks in advance for your help."

That does not sound good. There is no way for the oil to get into the water intake, unless a seal has gone bad, on the casing is corroded or cracked.
