so, jeff, you are the opinion that changing fuel filters is what is meant by
the term "tear down"?

btw, jeff, are you aware that commercial fishing boats have fuel manifolds that
make replacement of clogged fuel filters an on the fly event?

"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.

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?

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!
