Hi,
I have a 1985 25HP Mariner 2 stroke outboard. After a run to a
fishing spot I stop the motor and after a few minutes there is a
rainbow of a gas/oil slick on the water. After a few minutes is
dissipates. What is causing this? I do not want to be a polluter. I
can not tell where this is coming from. The fuel lines do not have any
leaks.
Does anyone have any ideas?

Nothing abnormal with your elderly two stroke.
