My dad has a 1996 johnson faststrike on a 18ft. stratos. The motor has very low miles and not abused at all. Regular maintenance. When he is idleling or letting it run in the yard on a set of water muffs, it releases an excess amount of oil and gas from the exhaust. Any idea what is causing this and what can be done to fix it.
Any help would be gladly appreciated.
Thanks a million fellows.
