After taking care of various commercial machinery, it struck me as very
slapdash the way most boat owners take care of their engines.

Yelp its down right laughable of some.

In some cases, it's ignorance... or listening to bad advice. In others
it's laziness or cheapness. I'm pretty tight with a dollar but if you
are going to own a boat IMHO scrimping should be done in a way that does
not lead to damage or premature repair/replacement.


... And compaired to the US Navy
PMS many companies are put to shame.

Well, the military has manpower to burn... they don't pay overtime! One
thing I will give full credit for is their training, that is second to
none. But in many cases, the U.S. military expends huge amounts of
manpower fixing things that ain't broke, taking apart things just so it
can be checked off and put back together.






I did a test on my gen set when I rebuilt it 5 years ago. Have many
hours now on it and Im starting to see soot. Think its just needs the
injectors rebuildt but... Im glad I have my old report to compare with
a new report.

Could be the injectors need adjusting, or it could be crud in the fuel.
You using 2mic filters?



I think they need new tips. Did not redo them when I rebuilt the
moter.

Why do you say crud in the fuel?

Because some types of crud will produce sooty exhaust, especially under
load. If the engine has a lot of hours & 5 years on it, then pulling the
injectors is probably a good idea.

Get 2 micron filter elements and a good water seperator. And while a lot
of people swear by "Algae-X" it sounds extremely hokey to me and I know
a couple people who have this and they still get crud... the key is to
use fine filters and change the element often.


When a heavy load item like the AC or water heater kicks on you get a
little black soot on the water, almost like turbo lag.... but its not
turbo charged.
I was thinking a poor injection pattern due to washed out or fouled
tips.

Yep, possible... Could also be timing or a governor adjustment. I'm sure
not a diesel expert. I am leery of pulling things apart, but it sounds
like it's due anyway.

several years ago, my son did his engineering internship for the USN,
developing software that analyzed vibration of various on-board machinery in
an effort to provide data via non-invasive means.

What were the results? Cheap temp sensors and automatic logging do
wonders for op-condition analysis. Vibration sensors can't be much more
expenisve.

Anyway I hope your sen had a good time working what I used to call the
gnomes of Mechanicsburg...

Thanks for a typical Doug King sailing related post - NOT

snipped off-topic, not a hint of sailing content post

Submarine sonar could do that no problem. So could the SQS-26.

Ahoy!

Amen!

Glory!

Doug,
Yes, he did have a great time doing this service for his country (he was not
paid). He did the internship as part of an advanced placement class while he
was still in high school. He's since graduated college and landed a great
job working as a software engineer for the largest communications company in
the world.
