Anyone ever seen this?

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

if you havent already id call the dealer you bought it from and talk to them, something doesnt sound right
 
Yeah, I'm waiting on the service manager to call back to set up a date and time. Sorry, I was trying to get my pictures to upload but couldn't get it going. Really bummed about it, I have the summer off and this wasn't how I planned to spend it lol. But not sure what's going on with it, I never lost water pressure or anything noticeable from the engine. It's Got me scratching my head.
