Chuck,

I agree completely with Harry on this one. The N/A engine will generally
require a lower pitch prop to get up to full RPMs so it won't be overloaded
at 1800 rpms. Those engines are tough pieces of iron. I have two of them
at 185 HP and would take that deal for the rebuild in a heartbeat. I do not
think anyone is going to care if the engine is 25 years old as long as it is
clean and you have the paper to prove it. I just wish I had freshwater
cooled manifolds but since the current ones have lasted almost 17 years I
guess I can't complain too much. I changing mine next week on the Port side
just due to your story as preventative maintenance and yes they are about
1K.

Need to make some final decisions about the best cure for my engine
problems.

Options a

1. Have current 6354 turbo Perkins rebuilt by Pacific Detroit Diesel.
$3600-3800, plus 10% markup to my engine specialist who can set up the
deal and
will handle transportation to and from the reman shop. Will need a new
manifold
for another $1k, and new innards for the aftercooler......(close to free
since
it looks like the aftercooler failed to bring down the engine and I
bought the
aftercooler several years ago from my engine guy).

2. Brand new Perkins Sabre tubo engine, about $14k

and here's where it gets interesting.......

3. Brand new Perkins Sabre naturally aspirated engine, about $10.5k

Especially with the super deal my engine guy is willing to arrange on
the
rebuild, I think I'd just automatically do the rebuild rather than the
new
turbo engine.

But, the difference between the rebuild of my old turbo and the N/A
Perkins
Sabre makes it a tougher call.

Anybody running a 6354 NA? I'd lose about 30HP, comparing the maximum
ratings
of the two engines, but I typically run about 1800-1900 RPM with the 165
turbo.

I might lean toward the NA engine if I'm not going to lose anything more
than
about 1/2 a knot, (the Perkins specialist says I might even go a little
faster
with the NA at 1800 than with the turbo at 1800....hmmm).

Another factor: Wife says there is another boat in our future. Not
necessarily
in the next couple of years, but certainly prior to retirement. She has
a few
items on her boat "wish list" that she thinks are missing from our
present
boat. General question: If you were considering a 25-year old boat,
would you
be much more likely to buy the boat and/or pay a few thousand extra if
the
engine were 4-5 years old vs. a 25-year old engine with 600-800 hours on
a
thoroughly documented rebuild?

Such a quandry.



Get the cheap rebuild and save the bucks for the next boat.
