i have a 1980 evinrude 115 v4 2 stroke. i recently noticed a wierd leak. after a day of boating, loaded the boat and went home. 1 hour later i noticed a leak of some kind running douwn the leg of the motor. it is coming from underneith the motor housing. it is very dark grey color ond has the consistancy of a thin grease. smells like grease or an oil of some kind. could this be to an excess of oil build up from the 2 cycle gas? any ideas? has anyone ever encountered something like this on their motor?
