Hello folks,

Recently acquired a used pontoon with the aforementioned Mariner engine on it.

When starting, I do see some exhaust around the cowling. After running for some time, it seems to disappear.

Is this common? Do I have a leak in the exhaust that tightens up once the motor has heated and expanded? Or is this a symptom of a possibly bigger problem?

Of note, this is about the quietest 2 stroke I've ever heard, and seems to run quite well,
