A few thoughts on "Aircraft Engines" vs. the regular kind.

1. I love the people who say they can buy an Aircraft Engine for some
small amount of money and bolt it on and go flying. What they mean is
that after decades of search they managed to flam some widow out of an
engine for a tenth market price, they bought some oddball no one wants,
or they have an engine that is such a mutt with no logs and bootleg
repairs even the airboaters eschew it. Good aircraft engines, such as
they are, are worth a lot of money if they are airworthy certificated
engines. If you have one, it's generally economically more
advantageously bolted on the front of a certificated aircraft.

We all know you can weld and machine about anything and all the little
tricks, or most of them anyway. There is no consistent source of safe
aircraft engines below market price. Even if you are willing to
generate very fictional logbooks, like most of the FBOs I know. It
isn't that hard.

2. If the Lycoming and Continental paradigm of large displacement
light slow turning engine was so great for aircraft, they would be
great for a lot of other things as well. Teledyne Continental and
Textron Lycoming have absolutely no interest in marketing or developing
their ridiculous museum pieces for any other markets whatsoever. The
reason is simple, no one likes being subject to ridicule. Which they
know would be the case.

3. "All the people who use an automotive conversion spend fifteen
thousand dollars anyway". You are comparing apples to oranges because
the guys spending like this are going all out and not doing any of
their own fabrication. And ignoring the fact that their per hour has to
be a lot cheaper because once done rebuilds have to be radically
cheaper.

4. "You are in all reality only going to fly it a few hundred hours
anyway". Well if that's the case, join a flying club (a real club) or
just rent an airplane.

There are others but that's enough for now.

Your ignorance never fails to amaze, maybe that is what you do to
people so you assume that is what all people do. (shakes head in disbelief)

Long stroke, slow turning engines ARE still used and designed all the time
in agricultural, industrial, and marine applications. It all depends on
where you want your peak torque at. In an aircraft engine, the best prop
efficiency trade-off is in the 2200 - 2500 rpm range and the most efficient
way to transmit power is via direct drive, hence engines are designed for
the applications in which they are used.

Not neccessarily. I recently passed on a pair of IO-540s with original logs
for $8000US because I have no place for them. They were still attached to a
bunch of airframe parts.

What other applications would be appropiate for air cooling? Keep it simple.

Apples to oranges? The bottom line is cost to get the project airworthy and
reliable. Wether it's spent on an orange engine or an apple engine, it's
still spent on motive power. They're both fruits.

4. "You are in all reality only going to fly it a few hundred hours

Justify whatever you have to. Rationalize whatever you have to. Bottom line
is that I'm going to do what I want just because I can. I don't give a f**k
about what anyone thinks.

Where are the long stroke, slow turning gas small boat engines?

In museums. Inboards ALL use autoderivative engines and ahve for
almost 50 years

Thank you for these pearls of wisdom. I'll go back and rip my brand new,
large displacement, slow turning, low parts count Jabiru 3300 from my kit
right away and replace it with a Rotax screamer at 5000 rpm, heavy gearbox
in front, three-way oil/water/air cooling labyrinth of pipes and tubes. I'm
in your debt...

Small boat motors turn small "props" at high speeds for usually not long
periods of time. Besides cooling is usually not a problem with a large
supply of cooling fluid! ;-)

Air cooled engines are now no longer made because of, well,
obsolescence, except toys for yupsters like Harley Davidson.

Air cooled engines no longer made? Look around you. Take a peek at your
lawnmower for example. Then go find a brand new piston Cezzna and squint under
the cowl.
