A marine engine has a crankcase having a crankshaft that rotates about a vertical crankshaft axis; a cover on the crankcase; and a cooling member disposed in the crankcase. The cooling member has an inner surface that faces the crankshaft and an outer surface that faces the cover. The cooling member is configured such that rotation of the crankshaft causes lubricant in the crankcase to impinge on and drain down both the inner and outer surfaces of the cooling member.
