Somehow I found this site:

http://members.aol.com/westernstar66/indianlisters.html

that lists a 20 hp diesel for $3250, a real bargain for a new engine
compared to most diesels for boats. These are low rpm diesels that
can run on vegetable oil and are very efficient.

So, what would you do for a transmission? Maybe you could use a belt
with an idler pulley that was lever controlled. Tension on the idler
pulley would sorta regulate the speed. Maybe the engine has a speed
control, I dunno. Reverse would be a real problem. These look heavy
but just cool as hell. I love simple stuff, great engineering.

Looks a lot like some of the old 1 lunger diesels in the Monterey fishing
boats and some of the other commercial boats in the 1950's.

Pep Boys Auto Parts had this 6KW diesel genset, electric start,
quiet cabinet, ISO900x certified, painted yellow but from this
Chinese company, for $1599 last fall. I'm running 2 diesel cars
and a V-8 diesel stepvan on used frying oil from Chinese
restaurants, so decided to buy one for the house in case of
hurricanes here in Charleston.

It's a great little genset, 120/240 60 Hz for the American
market. It turns 3600 RPM from its 1 cyl OHC 4-stroke diesel and
runs a LONG time on a single fueling. Its only headache is its
WEIGHT! The Chinese now seem to have VAST resources of HEAVY
STEEL and aren't afraid to USE IT in their products. It has
wheels for a reason. None is going to carry it off without a
fight...(c; The cylinder, for instance, isn't a cast iron sleeve
in an aluminum case...It's a CAST IRON CYLINDER, the old
fashioned way!

There's a compression release so you can hand crank it with the
included crank handle if the battery goes dead. Even comes with
a little AGM starting battery you can't pronounce.

I ran it on diesel for the first 20 hours to make sure it wasn't
going to be a return problem, but have migrated it, now, to my
cooking oil soup of 1 quart of mineral spirits mixed with 20
gallons of cooking oil and it cranks right up.

Whenever I crank it, my smartassed neighbor shows up with his
drop cord, the price I have to pay to run it 24/7 in
emergencies...(c;
I'll even have 220VAC hot water....

Only by allowing varying ammounts of belt slippage. You would get very
poor belt life. I have seen this kind of setup, My dad built a lawn
tractor with that kind of clutch. Had a transmission from the flap
mechanism on a B-17. It had only 3 horse or so.

Get your attributes correct. And there are variable transmissions for
belts. Some automatic according to speed. Variable width pullies. One
gets wider while the other gets narrower giving a bigger diameter.

Talk about mutually exclusive terms.

Correct...

CVTs (continuously variable transmissions) are being used in cars currently on
the market. My Honda Civic Hybrid has one for example.

My 250cc Honda Reflex motor scooter has a variable V-belt drive
on it. The pulleys are about 6" in diameter and have two sets of
3 weights in them that are rollers. When the pulleys come up to
speed, geared to the rear wheel, one set of weights flies out at
around 40 mph. The second, lighter set, flies out around 50.
This is dependent on how much throttle you feed it, how much
power it's transmitting to the wheel. If you are easy on it, it,
the ratio changes more quickly than if you are harder on it,
which puts pressure on the V-belt and keeps the pulley apart
(like lower gear) making the transitions come on later at higher
speeds. There's a clutch inside the engine that applies power to
the v-belt drive around 2200 RPM, 1800 RPM is idle on the 1-cyl,
250CC, OHV, 4-stroke engine you can hardly hear run or feel in
the handlebars. It's a beautiful piece of engineering, very
simple in design. Honda spoils it all by trying to get $83.16
plus tax out of the damned common small 18mm v-belt it runs on.
It took me a while to get the specs on the belt, having to
threaten them with a Magnusson-Moss legal action if they required
me to use only their way-overpriced OEM belt. I got a better
belt than the cheaply made OEM one for $11.29 at Advance Auto, a
more reasonable price. It's double-cogged, steel cored. I'll
change it when Honda says at 12,000 miles. I built the pulley
removal tool already from a website on the net. I'm also playing
around with different WIDTH belts, which will change the gear
ratio of the system. Wider belts will run at lower ratios,
increasing mileage past the 80 mpg I'm getting now at the expense
of takeoff power, which at 62 years old doesn't impress me like
it used to...(c; I'm looking for the LONG RUN on the engine,
even though it's a Honda.

I remember Dutch-made DAF cars from the 50's and 60's that had
two belts with a central cross-shaft drives on them. Their
pulleys varied in width, too, on v-belts. The belts were LONG as
I think the cars were rear-wheel-drive. Belt drive is nothing
new.

The Honda Silver Wing 600cc scooter also has v-belt automatic
drive. I rode one but didn't like so much engine weight in the
back. It's really stern heavy. The 250cc will go about 85 mph
on its rev limiter. That's probably fast enough around the
city....(c;

Run it as a generator and use it to charge an oversized bank of batteries.
With an electric motor you will gain variable speed and direction without
have an engineering nightmare.

I have been speculating about a diesel-electric propulsion for a smallish
sailboat. Does anyone have links to, or experience with, small electric
motors that are suitable for continuous use - most of my googling finds bow
thrusters and other extra machinery.

I am thinking of a fairly small engine, say 5-10 Hp, to be used mostly in
manouvering in and out of marinas, and occasionally coming home from a calm
sea. Would it make sense to mount the whole engine on the transom-hung
rudder? That way it could turn with the rudder, and give good steering in
both directions. When not in use, it could be lifted out of the water, so I
could use a decent size of propeller for it.

Would anyone care to shoot the idea down before I get too attached to it.
The whole project is on a dreaming level, I won't be building anything for
the next many years. But I still want to design it as if I was going to
build it some day soon...
