Yanmar industrial engine

[Tylerdurden]

I am looking for a slow turning diesel and came across this yanmar
TS series, I haven't found much of sales info in the US and was wondering if anyone is familiar with them.

I can get 19 continuous hp at 2200 rpm for the Rescue minor.
With the kitchen rudder it should be one trick ride.

I wouldn't call 2400 RPM low speed; maybe for a Yanmar but not in the greater world. More like "medium speed." On the other hand, it should be a fine choice. Their quality is proven.

we have a small Industial yanmar on a emergency dewatering pump at work. Pretty basic, not sure how marinizing it would work. The small kubotas may be a better bet.

The issue I am having is to get the HP at lowest RPM, Kubota is around 3400-3800 so its a bit faster. If there is another manufacturer out there who fits the bill I am looking for I haven't found it.

I am looking at industrial diesels for two reasons
First, Robb White hated Marine engines and their costs. He felt with a little thought any diesel would do and be well within reach of the common builder.

Second, I am trying to eliminate as much complicated crap as I can.
These yanmars are used in far out places because they can be hand started and will run much longer (slower RPM) than most other high speed diesels. Marinizing them isn't to much of a problem.

Robb loved the Rescue Minor and wanted the design to see its potential and I hope to continue with what he started so making it fit inside his wanted parameters is important to me.
So avoiding an expensive marinized engine is along those lines.
By using a kitchen rudder I can forgo a transmission and get my reduction via a polybelt setup similar to his. No need for reverse as the kitchen rudder will give me that in spades.
I haven't finalized the rudder design yet because some decisions are waiting on the final construction design of the hull but I hope to be prototyping one late February.

Okay, I got your picture.. Sorry, I didn't meant to give you a run-around..

No problem, its a complicated mess right now. Setback after setback.
It seems they come when I deviate from the original plan. So I am steadfast in it now.

Have you given any thought to one of the Chinese diesels? They are similar in apperance to the Yanmar and Kubota horizontal singles, but much cheaper. The problem is that their quality is all over the place. There are lots of horror stories out there about lasting only 500 or so hours, and others that they run for years.
I have a Chinese 185 hopper style on my cordwood saw and I love it. Lots of the Amish sawyers around here use them for power on pumps and slabwood saws etc, and those guys are no fools. It is generaly thought that if you stick with the better known "Changfa" brand, you'll do OK. Right now on eBay there is a 30hp (!!) single for sale from Quebec. It weighs all of 600#, but that puppy would twist a big ol' wheel in a launch.
I have seen pictures of the used in Asia on boats both with the "long tail" type drive, and with primative types of outdrives.

Is there any distributor for changfa in the US?

[Lew Barrett]

You have asked the right question here tylerdurden.

[moTthediesel]

Google "Listeroid"
There is a forum for Indian built Lister type diesels and they also have lots of info about other slow and medium speed diesels including Changfa's.
You might find a US sorce there.

When they say "less vibration" you should ask "less than what". I have had experience with 2 different single cylinder yanmars. One was aircooled, driving a 23ft keelboat. Damn near shook the boat apart and made it a horrid place to be with the heat, noise and vibration. The other was water cooled, driving a generator on a larger boat. Noisy, dirty, vibrated like hell. Like a road worker with a jack hammer down in the lazzarette. They are not a nice, slow turning old fashoined diesel. Leave them on farms pumping water I say.

I am finding that out, "stationary use only" and not legal for vehicle use. Thanks for the input.

If it says marine on the product LOOK OUT!!
Its like parts for motorcycles. A velocity stack at motorcycle shop price is $212.00 at car parts price $27.00
A fender for your boat trailer $30.00, at motorcycle prices $469.00

Everything that you buy for your boat if bought at a place that does not say MARINE you will save money.

China Diesel!
Now there was a thread to read! I wonder (not enough to actually look) if it still is accessable?

"reduction via a polybelt setup "
Where would one find information about how to do this. I have seen it in some pictures but never any real info on it.

Check out your local bearing supply house,I prefer Kaman because I have never had a stupid counter person at any I have gone to. Ask for Gates drive design manuals for the Powergrip and Polychain series belts. Just like the motorcycles run. What you use depends on the design speed you need. I have done some seriously demented things with these belts and they always perform. Those two books will give you all the info you need.

thanks for the info. I will have to check out those manuals.

Here's a link covering the Listeroid engine. Lot's of cool other stuff as well.
