Probably only interesting as ancient history but here in Australia,at least,it was routine to use pre war [ww2 that is,my how the wars have flown] 4cyl side valve auto engines in marine and other,notably tractor and small sawmill applications. Model A Ford, and Willys Jeep were common and I have seen Dodge 4. The Dodge/Chrysler sv 6 was used in a large fleet of hire cruisers nearby,70 odd vessels in all. They were crude,low speed engines with extraordinary long lives in utter neglect provided they were fresh water cooled. They were geared to run at max. torque,say 1200-1500rpm with a 2 or 3 to 1 reduction marine gearbox separately mounted via a short cardan shaft. This gave a really good slow prop speed for min. slip and large wheel dia. My old prawn [shrimp to you guys] trawler had a Willys and the pulling power developed was remarkable considering the small engine capacity. It was old when I had it and STILL lives on as a private vessel. Repro engine bits are pretty common from Asia and I believe it finally got a heart transplant. I kept the fuel clean,the oil changed and the cooling water abundant and it worked for thousands of hours with a nice puttering dry exhaust note that let other trawlers know who else was up and doing at 3am.Now the problem with all old engines ,whatever the application,is that they were designed for leaded petrol which protected the exhaust valves by forming a soft seal. I can't say how good all the fixes are going to be but I can still buy a re-built willys sv 4 here in Sydney and I know it will survive anything except salt water. Andy Wilson

Beats me, I thought that they used gears for reverse. That's what I get
for assuming. :( Ok I'll go with the Geo Metro engine. :)

I guess the Goldwing has change from my younger days (70s) when the reverse
in my Goldwing was run by the starter. Put it in reverse and press the
starter button. Only good for getting back away from a curb or such, not
for long term running.

Has that changed? If not, I can't see that working on a boat too well.

Peter, time is goin by to fast for you, A year or so back was Jan/Feb 97
issue 134.

I too suffer from time acceleration and too few years left with way to many
boats still to build.

It is far less damaging to the environment to use an existing power

IWhen I was touting the Hankinson/ Witt book "Inboard Motor Installation"
earlier I didn't make it clear that it is mostly about converting automobile
engines to marine use. Last time I looked most of the Volvo and Mercuiser
blocks are GM engines with marine stuff on them. You can get parts, including
a long or short block right from NAPA.

If you look at manufacturer's specs on an industrial engine you will note that hp rating varies greatly with service factor.
Marine service is the worst because there is no intermittance to the load. So your 1/3 throttle rule is probably not far off.

Perhaps. Remember, though, that such small engines are also short-lived even in their intended use. Two engines that
have a reputation for durability are the horizontal opposed Subaru and the V6 in the Nissan Quest. The Subaru is a
favorite for aircraft conversion. The Nissan engine just seems to last forever.

None of the fuel injected engines are tolerant of bad fuel. I always dumped my leftover race gas (2-stroke premix) into
the pickup tank after a race to avoid putting old fuel in the bike. First time I tried this in a fuel injected vehicle I had to be
towed home.

Mount the prop on a separate shaft with it's own thrust bearing. Connect the cv shaft with a spline coupling just like it was
going to a wheel.

Other engines to consider are the V-twins such as used in the Japanese Harley clones. These range from 500cc to
about 1500cc, low speed, shaft drive and mostly equipped with shaft counterbalancers for low vibration. It's been awhile
but I recall that the drive shaft was sealed at the back so you could probably adapt a prop rather easily. The drive shaft
housing is designed to take thrust through it's gimbal at the transmission. The shaft, however, must float.

One thing that always kept me away from motorcycle engines was the price of parts. If anything goes bad you might as
well get another engine.

I've heard the same thing from folks wanting to adapt auto engines to
aircraft. It seems that going down the road at 65 mph doesn't put much
of a load on most engines. So you may want to limit the throttle to 1/3
of maximum.

Then I wonder about the really small displacement engines. Like Geo
Metro and the like. You would think that they would spend more of there
lifetime at closer to max throttle??

The only bad things about using a motorcycle is that they usually have
complex carburetion systems that are very fussy about the quality of
fuel they get. Not very tolerant of water in the fuel.

Take a Geo Metro engine/transmission package. Have the differential
welded, and plug one of the drive axle holes, and away you go. :) (not
much for power though.

What would you use to take up the thrust on the propeller shaft??

There was an article in Woodenboat a year or so back about putting a
small auto (Suburu?) engine is a boat. Both the article and the
responses in subsequent issues raised a lot of points of interest.

I think it's one of those areas where something can be done right and
have great success and long life, or poorly and have some success for
a short time.

Motorcycle engines will work fine as long as you derate them substantially. Engines of this type are designed to output
their rated power for seconds - not hours. Water cooling is preferred as this allows you to use more of the available
power if you increase the cooling capacity.

>how about generator powered electric motor????

Electric motors are heavy and most folks don't like mixing water and electricity. I suppose there are some applications
where this would do fine.

Virtually all (gasoline) stern drive an inboard applications are automotive conversions. Again, derate the engine for
continuous load. I read that some fishing vessels on the Oregon coast use engines out of wrecked autos. They figure
that replacing it every year is cheaper than maintaining a more expensive marine engine.

I've seen workboats that used the engine and transmission from a car or pickup. Most looked like they were older than
any outboard which says something about durability. I'm not sure how one would adapt a front wheel drive transmission
though. Perhaps just locking the differential would be enough.

I was just wondering the other day how a Honda goldwing engine would
work. Flat four, quiet, water cooled, shaft drive, 5 forward speeds and
reverse. :) I don't know the details of the shaft drive, whether the
shaft is dry or wet. If it's a dry shaft, then it shouldn't be too
difficult to connect a propeller shaft to it, but if it's a wet shaft
(in an oil bath, or lubricated by the engine's oil system) then it would
be a bit more difficult.
