Motor is a '98 Johnson Venom 200. Owned less than a month. Taken it out less than 8 times. Today was running wot for about 15 miles. When i slowed down I started to here the engine knocking. Pulled the cover to find a milky oil or grease substance had leaked out. The leak is coming from the left bottom side of the engine. New to outboards and I need some suggestions. Thanx! (Crossing my fingers).![]()
