I looked at a 1990 Honda 10 Hp that is for sale. It has never been on a boat and looks new. Starts great, idles a little great but responds well to throttle. Last time it was started, some oil came out the "pee hole"... There are three hoses that go into that hole, and one of them comes from a port by the oil check/fill hole. The oil was overfilled (he has never changed it and it looks brand new!); is this the source of the oil that was peed out? It stopped peeing oil after about 30 seconds. Thanks for any help.
