Re: Yanmar 2GM20 steam through the Exhaust
Could be an almost clogged water injector in the mixing elbow -- there isn't enough water flowing through the system to keep the elbow cool, hence the steam. Take the mixing elbow off and see how much crap has built up inside. Also, try blowing into the nipple where the water hose connects to the elbow; if you get any back pressure then it's probably time for a new elbow.
Never forget them. Do something to prevent it from happening again.
