Love those old 2 stroke Detroits!
Nothing like the sound of one of those screaming away....

Here is a great site for marine diesels:

Those old Detroits will always smoke more than a modern design.
Black smoke = fuel rich (worn injectors )

The 2 stroke Detroits have NO injector pump, so that is not an issue.

Those engines will suck as much air as they need - I put zero creedence
in
the not enough air theory.

Again, those engines awlays are pretty smoky. If the injectors are OK,
and
you are running diesel with a high enough Cetane, learn to love the
smoke.

Bull****.

I have 6V92TAs and mine do not smoke or foul the transom AT ALL.

Its all in them being set up correctly, in proper tune, and not having
maintenance problems of one kind or another.

If they're smoking something is ****ed up.

I've yet to see a Detroit 2-stroke that I can't stop from smoking, unless
the compression is low - in which case its immediately obvious on a cold
start and the only fix is a rebuild.

Well excuse me all to Hell, asshole!
My experience in DD 2 strokes is limited to trucks and farm equipment, and I
have seen a ****load of them smoke over the years.
**** you and the **** heap you rode in on.

===============================================

Karl's right. When they are in good condition, they don't smoke.

I'm surprised no one has mentioned taking a look at the intercoolers
(assuming it has them). They can definitely restrict air flow.

They're aftercoolers (10:1 odds given the year) and getting to them requires
pulling the blower, which is a major pain in the ass.

That is the purpose of the airbox/airhorn pressure test I asked him to run.

It will RELIABLY indicate if the aftercoolers are fouled, and you're right -
this is one of the major reasons for this particular problem.

Pulling the blower without KNOWING the coolers are fouled sucks - if you
take it all apart and they're CLEAN you just did 8 hours of work PER ENGINE
- or more, considering you now need to retune them as well - for nothing.
