Huh? Diesel engines don't last 800 hours before major repairs??
 

The claim has been made by a poster on this ng who calls himself "steve" that
diesel engines as used on commercial fishing boats are often torn down for a
major overhaul after every trip to sea, about 700+ engine time.

Anyone here have experience with diesel engines in commercial fishing boats?
do those guys really trust their lives to engines that won't go even a thousand
hours? Anybody know why they do this?

Or is "steve" out to lunch?

A USCG boat in this area had to rip out and replace a Cummins turbodiesel
with just over 1500 hours. Warped head among other problems. They were
not amused with this "life", from what I was told - but they also did the
R&R themselves in a bit over 6 hours (!)

I think that pace would be considered "in earnest" :)

Is this joxie the same person who claims that it's impossible to clean
the injectors of a diesel engine? Is this the same joxie who claims
that commercial fisherman go to sea for a month at a time on a single
engine without even checking it before they leave? Yup, that's our
idiot joxie.

"steve", I was just taking your words at face value. Am I the only person on
the planet who has done so in the last two decades?

tell us again that diesel engines as used in commercial fishing boats need to
be "torn down" for a major overhaul after every several hundred hours usage,
and how drunken, nervous crew "clean the fuel injector plugs" the night before
leaving just to be sure.

See, you don't know how to read. I never said they need a major
overhauy every several hundred hours. I said they will often do a
teardown while in port between long extended voyages at sea. If you
think that's a wrong statement, you are an idiot. Just like if you
think it's it's impossible to clean fuel injectors, you are an idiot.

Joxie, you are too stupid for words.

A rebuild is done when necessary (obviously). I have heard that a 2-stroke
Detroit will last around 2500 to 3000 hrs (according to a specific owner).
Now in this case the owner I was talking to eventually traded from a 6-71 to
a large bore Isuzu marine diesel which he swears had over 4000 hrs on the
clock. Disney world would do a rebuild on their launches (3-53 Detroit's)
every year but then in the late 80's switched to Perkins 4-128(?) because
they felt the service time was twice that of the Detroit's (4k-5khrs). Now
in reference to the poster he may have been talking to somebody that only
had one ship (with a single) and they could not afford to brake down and
loose a load. So the cost of a rebuild would be much less then the lost of
a catch. Most commercial companies collect an oil sample at each change and
monitor the material in the oil. Companies like Blackstone can tell you
more that you would ever want to know about your engine. They can specify
oil change intervals, leaking gaskets, bad injectors, warn cylinder sleeves
and so on. So it is reasonable but I suspect its not the norm...

For the environmentalists, Diesel fuel is easily biodegradable. If fact
without additives algae grows in the tank and lines. This algie and other
debris builds up in the tank and lines and and the fuel filters need to be
cleaned and the injectors need to be inspected and cleaned after extended
use. Also, when a boat is subject to heavy seas everything tends to hit the
filters. So when you need the engines the most your filters clog!

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

The normal rebuild interval for a naturally aspirated (non-turbo)
Detroit 671 is in the range of 4,000 to 8,000 hours for an engine in
moderate service, that is well maintained, and has not experienced
cooling issues, etc.

"Every trip to sea" could mean a month for some fishermen. Regardless of how
many hours are put on the engine during each trip, I'd think it would be
foolish not to do major preventative maintenance. Ever been 200 miles from
land?
