Since I seem to
have started this repower thread, I'll tell you why we
have decided to repower. As with any decision, I have
multiple reasons that have influenced our choice.

Our Perkins Prima has
4200+ hours, and has had various issues in the year and a
half we have owned the boat. Currently we have a overheating
problem that we cant seem to completely cure. If I keep
throwing money at it, we will probably eventually figure it
out, but who knows. The wiring harness for the entire engine
is old and brittle, and really needs to be replaced. The
engine panel warnings are not working, the tach just went
out, and a new panel is quite expensive. To rebuild the
engine, fix all the other bits and pieces, is going to cost
about 3/4 of the price of a new Yanmar. Part of the problem
in the USA is the cost of parts and labor doing a
rebuild.

We are about
embark on a 10 year circumnavigation, and the thought of a
reliable new engine with a warranty for 25% more $$$ than
rebuilding an old one seems like a good deal to me. I also
suspect when we sell the boat after our circumnavigation, we
will get a much better price with a mid time Yanmar vs a 32
year old Perkins with 7000 hours.

I guess only time will tell if we are
making the right choice, but I'm comfortable with it.
Also, we should be back on the water in 2 or 3 weeks, but
with a rebuild, we would probably loose most of the summer.
In our case, we have spent the last year re-fitting the
boat, are ready to go, and it is worth a few $$$ to not lose
our summer of sailing.

Frankly, I am at a loss as to why a person would
change an engine in the first place. We have the Perkins TMD
22A Turbo and it runs like a gem. I can still reach the hull
speed of over 8 knots and I can still power into a 30 knot +
head wind and still make way comfortably. The engine has
proved to be very reliable and economical to run. If you put
two identical Amel's side by side, one with a
Perkins/Volva 80hp and one with a Yamnah 110hp and ran them
flat out, I doubt if you would see any difference except a
larger hole in your pocket.
It is my opinion one would be better
of spending the money and giving your existing engine a full
overhaul. The Perkins is a very good engine and if the
maintenance is kept up, like any engine, it will provide
many hours of service. I know I can get parts anywhere in
the world so why bother?
Just my two bob's
worth.
