What does a pair of complete diesels go for installed assuming that I

Heh, project boat indeed.

I think the first step is to find out what kind of engines and
transmissions it had originally. That will be the easiest repower and
you may be able to salvage the original wiring harnesses, instruments
and controls. Those are non-trivial expenses. After that, start
searching the web for a pair of rebuilt engines, preferably with
transmissions. If you can get all of that to come together you might
be able to do the job for $30K total.

If you start from scratch with new engines it's a whole different ball
game. I assume you want to be able to run on plane at decent speed?
If so, you'll need high performance engines, no doubt turbo powered,
and relatively light. I'm guessing that a pair of 450 to 500 hp turbo
Cats would get the job done. New with trannys they will be $40 to
$50K each plus a lot of rewiring, instrument panel work, and other
labor. You may also need new shafts, struts and props. More big
$$$s, total job most likely over $100K, possibly well over.

What about a generator? You'll need that and something suitable is
likely to be $15 to $20K installed.

One comment about the 6 cylinder Cats. Great engines, but damn are they
noisy! I don't mean exhaust noise, but major engine room clatter when
running at cruise. Unless your engine spaces are well insulated, all sounds
are drowned out by the engine clatter. My Egg had the 450 Cat turbos and I
could never hear the turbos spooling up ... just the engines. I think the
V8 Cat diesels are quieter.

That's one nice thing about Volvo diesels. They are much, much quieter.
Put them in an insulated engine space like in the Navigator and all you hear
is the faint sound of the turbos spooling up above a soft engine background
noise.

There used to be a guy who had a 34' Egg with the same Volvo diesels that
are in the Navigator except they were the 320 hp versions instead of the
Navigator's 370 hp. Boat was fast, quiet and he never had even a minor
problem with them in the 5 or 6 years he had the boat.
