I'm running a new Mercury pro xs and probably have 10 hours at most on the motor. I noticed this the other day coming from the exhaust relief port. Not sure if it's leftover from part manufacturing or something way more serious. It seems to be plastic/resin. Motor has been running just fine. Let me know
