If I were you, I'd definitely capture this one.
Looks as if it has the original primer and a really interesting spark plug - certainly not one that I have seen before.
It's probably made after the introduction of oil / gasoline mixing i.e. 1910 - 1911.
And it doesn't look as if it has been stored out in the weather so it's probably going to be easier to free up.Looks like a 1 in carb will do the trick.
Happy haulin'

Sure looks to me like a diesel injector on the top. I don't see any spark plug. |

Thanks for the replies so far.
From what i can remember looking at the engine, there is a spark plug (or glow) at the rear of the head. (marked in this picture)
One of the blokes i work with reckons its a Lister marine. but again i can not find anything on google!

If all I could see of this engine was the very top I'd think I was looking at my 1970's Yanmar diesel. The setup looks identicle right down to the shape and thickness of the strap securing the body as well as the apparant diameter of the body. The flats on the body above the strap are for disasembling the injector. Obviously this is a much earlier engine but the similarity is remarkable. The injector(?) is held in by the strap secured by the two studs to either side of the body. The body is not screwed into the cylinder. It just drops in. My injector has an O-ring at the base of the body to complete the seal. I'm not sure they had O-rings or the lathes required for the extremely close tolerances of a diesel injector unless this is a much newer engine than it appears. Probably a good soak with penetrating oil will be needed to free it. |

It sure does look like an injector Could the engine have been started on gas then switch fuels once warmed up? |

I agree with miro,go ahead and get it.That looks like a 'piston break' or 'compression break' ignitor that is hard to find intact. |

Hi all,
Thanks for the help with this, bit of an update. I managed to get back and have a look at this engine again. Its mine now, just have to pick it up!
So I found a plate. Looks like we are looking at a Chapman marine diesel.
Though I know nothing more than that. And I can not seem to find any information or pictures of this model. In the picture I can not make out the lower line of text.

That's a very rare engine you have there. The only Chapman I had seen illustrated was the 15hp, introduced in 1933. There was a 10hp lightweight advertised from Sept 1937, but no photo. Is yours big enough for 10hp?
No technical data on the 10hp, but the 15hp was a petrol start type. Quite a complicated and heavy engine.
I can't recall seeing a diesel with a non-detachable head either. Most unusual.
More photos would be appreciated.

Wow! John Forrest described to me a delivery trip from Sydney to a port south (Narooma?) in an open boat powered by a Chapman diesel. John was the apprentice and naturally was given the delivery trip to undertake. He said that only 6 diesels were built! John said they were a bit experimental. A surviving Chapman diesel is therefore well beyond just being rare - I have never even seen a photo. They started on petrol and had a carby and magneto (as did the much bigger Kelvins), and then switched over to diesel, or oil. John said starting was easy. I do have some brochures on them and will dig out and scan. |

Hi Eric,
I thought you would have caught this first time around. The flywheel and the crankcase are a dead giveaway as being from the Chapman stable.

Eric, it would have to come close to 10hp. its large and heavy. From looking at other pictures of 10hp vintage engines, its very close.
Andrew, Lets hope it is indeed one of those surviving engines! would be a very lucky find.
it is interesting you mention about the petrol starting. The object that i had marked with a red ring in the previous photos looks to be a spark plug. when i had a closer look at it the other day i was sure it was. unless glow plugs used a porcelain jacket??
The owner told me the engine was in the shed when they purchased the house. over 60 years ago.

This is the 15hp engine. Weight with reversing gear as shown is 1800 pounds or 816kg.

Seems to be a lot of similarities to the 15hp. Maybe it is the 10hp after all.
Have been trying to look for more info almost every day now. Looks like it will be tougher that I first though to find some in depth information on this engine.
Would love to know its history. |

Hi,
I have to disagree a little. I think it resembles the engine I first suggested.
See the link : http://www.smokstak.com/forum/showthread.php?t=112243
It may even be using some of the same parts.
Regards,

Hi there, I am the Grandson of John Forrest and I can recall the story you mention below. He was alone in the boat and the lights went out. He lost sight of the coast line and was in a difficult position. He mentioned about 30,000 times how reliable the engine was and the faith he had in not getting stuck in the high seas. Anyone who knew or met my Grandfather would know his love for these engines (Chapman). He would describe the engines as being very easy to start and reliable as ever. He often held my arm nearly breaking it demonstrating just how they started. I must have told him a thousand times that my arm is not a flywheel. Anyway just thought I would place a little light on your interesting topic. Nice find, would be great to see in action.

A great story Scott. They certainly sound like a great engine.
Does anyone have any scans of any documents on this engine? I have a few on the seadog and the block of this engine looks identical. The head looks to have a few differences.
Picking it up in 2 days. Lots of photos to come. Hopefully I wont have to find a pump for the fuel! |

When I get spare minute I will have a look for you, I have a lot of documentation and manuals. Is there a particular name/model that you can reference to assist my searching? |

That's very kind of you, much appreciated.
At the moment all I have it the details on the plate:
Chapman patent diesel engine.
In the picture I took the lower line of text on the plate was a bit too blurred to read. And I don't think its the 15hp diesel.
Will have more info in a couple of days. |
