Smoke emitting from the engine...

My Yanmar diesel has been very good to me. Knock on wood...

I have been in more than a few tight situations and this engine has saved the day.
And now it looks as though my Yanmar is in need of some love.

Jess and I took the boat out last weekend and started smelling smoke after about 10 minutes under engine power.

When I removed the engine hatch, I saw black smoke rising out of the mixing elbow. Here is an image of the front end of my 2GM20 diesel.

The mixing elbow is just out of view, but it sits on the top left corner of this photo. This component looks like hell, very rusted out... But it always has looked bad. Now it is also smoking when I bring the engine up to max RPM.
I will keep you posted - I am hoping this is a reasonable job in terms of price and effort...
