hi just unwrapped my boat and the engine has oil leaking ..not much.. where the leg connects above the fill hole for the lower unit. oil appears heavy.not light like fuel-oil mixture . took the engine cover off and the base around the engine is clean and dry. don't think the oil is from the lower unit because the leak is just above the oil fill plug. motor was stored in the down position all winter. any ideas where this black..sort of heavy oil came from ? thank you
