Brent,
I have had a Yanmar YSB12 for 15 years now, and one thing I have had
to re-learn a few times is don't be too quick to dismiss the possibility of a
cooling water supply issue. Just because you can see water coming out the
exhaust does not mean that there is enough. The culprit in each case on my boat
for white smoke was a partial blockage caused a bit of whatever that was sucked
in and lodged somewhere. The addition of a raw water strainer narrowed down the
possibilities, broken impeller bits notwithstanding, but I have since got
chunks stuck in various places including in the strainer housing itself where
it could not be seen. I would recommend a strainer oversized in hose diameter
to prevent that last one from happening. Anyway, the bottom line is make really
really sure there is lots of water flow before you fix something else.

Greetings all.
The 1GM10 Yanmar on my 27 began to give me issues last summer. The usual
complaints, hard starting, ran well once it was going. I replaced the filter in
the fall and my next move is to replace the old fuel and clean the tank.
But judging from the white smoke in the exhaust I'm thinking the injector spray
pattern is off and I'm getting some dripping. I'm planning to extract and
clean it or replace it.
Any tips from those who have done this would be appreciated.
