A friend recently replaced his old Perkins 4.108 with a new CAT (somewhere
around 50-70hp) in his Mason 43. He says he's got about $15k into it and
has done nearly all labor himself., but did a very thorough and nice job of
it (new muffler, all hoses, engine controls, panel, etc.)

I've got estimates on both rebuilding, or replacing my Perkins 4.154 with a
re-manufactured engine (w/ exchange for the old one). Both around
$4500-5000 not including removal/installation costs or freight (significant
if not local). The re-man. engines don't come with the marinizing stuff
(you have to use you old or supply new alternator, raw water pump, heat
exchanger, engine mounts, etc.), and the same is essentially true for
rebuilt. The rebuild cost assumed that the injection pump and major
components (i.e. crankshaft) were in good shape.

Well, we're inching toward our purchase, and the 1980 boat it seems likely
we'll buy has an engine of questionable condition. We'll have an engine
survey on it and the generator if we succeed, but the broker asserts that
diesel prices have come *way* down in recent years.

So, the question arises - if I had to repower, in a 60-80HP class, without
the installation costs, what are the typical available engines and their
costs? I didn't discover any way (without getting into a discussion with
a
salesperson) to find that info on the web, at least about Yanmar...

And, if you've done such a repower, what was your experience? Does more
power fit in a smaller space (without resorting to turbos, which I'd
prefer
to avoid if I can)? Is it cheaper than, say, 5 or 10 years ago?

Much of the discussions I've seen about repower seem to automatically
include a transmission. Is that because it's easy and cheap while you're
in
there already, or because there's incompatibility issues?


Thanks.
