Having changed the oil in my sail drive about 4 hours of motoring ago it already looks yellow (as indeed it was when drained). However no water came out. Can anyone with a Yanmar sail drive comment of the quality of their oil when changed? I am getting conflicting advice ranging from change the seals to that’s perfectly normal.
