Give Norm Gustafson a call (360) 823-6357. He used to be in charge of big
diesels (Catapiller) locally, and he taught a diesel class when he was a
member of RCYC. He can give you advice over the phone, and if you want him
to work on your engine, he'll do a good job.

On Tue,
If you're looking at blue smoke it's not as likely to be the injectors.
Injectors usually get linked to black smoke / an overly rich mixture.
Blue smoke is more likely compression related or somehow the lube oil blows
by the rings and burns (It seals-up as the metal expands upon warming up)
But it
My Yanmar in my C&C44 emits a small cloud of white smoke when I first turn
it over after sitting idle for weeks or months, but never blue or black
smoke. My engine had a partial rebuild in 2007 which may have eliminated
some of the issues of an aging diesel...
I hope that's helps in some way?

Have you checked your air cleaner/muffler for oil saturation? My engine
has had slightly elevated blowby which caused more oil to be pushed past
the separator screen in the valve cover. The oil is drawn back into the
engine by intake suction during normal ops. When the engine was shut down

My 4 cyl Yanmar (non turbo) has begun to smoke a lot more when first
starting. It is a blue smoke that mostly goes away when it warms up. It
starts very easily and runs smoothly with good power.
I would love to hear your opinions of possible problems and cures.

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

Thanks Jerry,
An electric motor would be great for racing but a retrofit like that is far
from within my budget these days. I'll get by with the existing setup as long
as I can.

If water is getting into cylinder that could explain the hard start. When
engine heats up water is turned to steam and engine will run but with steam in
exhaust. If water is getting into crank case you will see it in dip stick as
honey like clumps. You can often hear a blown gasket as well.
Have one in my 27V. Spoke to a Yanmar dealer at NY boat show. They can't sell
1GM anymore but can exchange for new if you send in old one. Don't know how
much. I'd be surprised if it's a head gasket. I think if mine went I would
put in an electric motor. J boats has one for the J88 that wou
Thanks for the terminology correction, yes, it's raw water cooled. It's just a
wee single cylinder unit.

Not to be an alarmist, but white smoke usually means a coolant leak, such
as a blown head gasket. Take a sniff of the exhaust. If it has a sweet
smell, you've got an internal coolant leak. Is your coolant level going
down, with no apparent leak?

You can remove the injector from the block. Turn it upside down, reconnect
to the fuel pipe, turn the engine over until the injector starts to spray.
Pop, pop, pop. Watch the spray pattern. It should be a clean, wide cone
pattern, equally aerated, fine mist. This is a test you should do before
Send the injectors to a diesel repair shop. They know what they are doing.

The 1GM10 Yanmar on my 27 began to give me issues last summer. The usual

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 t
