went to look at a 1997 legend boat, with a 200 mercury on it. i dont know a whole lot about it yet. its parked at my father in laws and belongs to someone he knows. we ran it just for a second until the hose adapter broke. after shut down smoke kept coming out a small port next to the water pump outlet. when i blew into the hole it forced the smoke out a port on the bottom of the foot. the motor only ran for about 4 seconds when i shut it back off because of the adapter breaking. anyone know what that smoke is? it slowly wafted out for about 2 minutes. also does anyone know of any issues with late nineties mercury 200s?
