I am hoping to find some information on where I might be able to purchase a Blaxland-Chapman Pup engine in the U.S. I read about a 2 1/2 HP version of this engine in the Sept/Oct Wooden Boat Magazine which was owned by Alan Graham(located in Goolwa, Australia), and I became very interested. It was a main article about steamboats on the Murray River in Goolwa.
I intend to use this engine in my 16 foot wooden launch - a 1920 Gilbert Launch V-hull, made in Brooklyn, NY. I live in upstate New York and hope that there are resources for this engine a little bit closer to home in the U.S., without having to look in Australia - although any information would be appreciated. I can be reached at cmbarry@attglobal.net. Thanks!

Hi Chris, I'm located in Melbourne, Australia. Is there any reason you particularly want a Chapman/Blaxland engine? I'm a big fan, but having said that, they're a rather basic affair, certainly nothing unusual.... Blaxland-Chapman single cylinder engines came in a number of sizes:
Standard Pup - 2 1/2 HP
Master Pup - 3 HP (I have 2 of these)
Blaxland Pup - 3 1/2 HP
Super Pup - 4 1/2 HP (the 'super' is also featured in that copy of wooden boat, in a 13ft boat of the same name - and it's over-powered!)
I would consider a 16ft boat, especially an older, heavy hull, to be under-powered with the 2 1/2 HP engine.............. I'm hoping to build a 16ft double-ender next year, strip plank construction (fairly light) and I'll be putting a 4HP Penguin into it....
As to availability, they're pretty easy to come by down here, but I seriously doubt that any were sent to the US........
Good Luck!

Chris,
I would agree with Rob that the Blaxland-Chapman Pup engine is a nice engine... but comparible to many that are more available in the US.
If hang around this site and check the Antique Inboard category of the classifieds, as well as ebay and your local gas engine shows, you will discover that early inboards are not hard to find.
Good luck.
Regards,
Andrew |

Hi there, I have just acquired a CHAPMAN MASTER PUP, I live Bribie Island,need help,eg. looking at flywheel should it spin clockwise, the arrow shows anti clock, I assume it is 2stroke?,timing seems way ahead of T.D.C.seen one on U tube seems to pump water through exhaust? |

Jackol, I'm not sure about the differences between the 'Pup' and the 'Master Pup' but you may consider this: The Blaxland petrol motors are 2 stroke (32:1). The twins (and I understand the pup, are set up to run in either direction with timing adjusted by turning the magneto which has two lock positions. For the twin the clockwise running position (looking from the front and opposite to the direction of the arrow) is with the magneto perpendicular to the crankshaft and the magnto is offset from perpendicular to run anticlockwise. A well tuned motor can be reversed without stalling by slowing it to just above stall and swapping the magneto position. You can thus set your motor to run according to the direction of your propellor. The standard exhaust receives cooling water from the outlet at the top of the block into the top of the muffler. The water and exhaust is mixed in the muffler and I've not heard of problem of water coming back into the manifold or cylinder. Good luck with it and enjoy life with a Blaxland! |

Jackol, The Master Pup is 3 HP. As Laurie said the Fuel mixture is 32:1. Do not use Outboard Oil!!
The Flywheel on that motor is on the rear of the motor. It faces the Stern of the boat and runs Anti-Clockwise.
You could contact Allen Graham at Tourbul or Stan Wood in Caloundra ( hd45wood@y7mail.com ). They should both be in the phone book. The water is in the exhaust to keep the exhaust cool and also to silence the motor as well, plus it is an easy way to get rid of cooling water.
There are plenty of others here as well that can add their bit.
Cheers,
Dave |

I meant to add. The timing is 2 inches before TDC, measured from the TDC mark on the flywheel circumference.

I have restored a 4.8 metre wooden boat origonally built in Portland and design came from Popular Mechanics 2 were built , I believe, and is powered by a blaxland twin . Boat and engine done very little work boat first registered in 1970 used to go off Indented head long line fishing . obviously engine tanks prop clutch etc all bought togehter .
Are there any blaxland experts in and around Geelong and Ballarat District so I can get assistance with the engine checked and started . No cracks in castings, spins fine mag has good spark rebuilt carb, all seems in order??

David, I noet your comment not to use outboard oil in the Blaxlands. I have used 1/2 outboard oil and 1/2 50 grade oil to make up my 32:1. I mix it with premium unleaded. Is this likely to create problems for my donk? Laurie |

Laurie,
This subject has been well and truly dealt with in earlier postings, the link to which is below.

DO NOT USE PETROL WITH ANY ETHANOL CONTENT.
Cheers,
Bruce. |

Hi Laurie, No it will not create any problems as far as lubrication goes. The main problem is that the 2 stroke oil does not completly burn and will at worst foul the plug and leaves a very sooty residue on the hull at the exhaust. It is designed for the modern High Speed motors. Valvolene make a single grade 30 weight oil. Penrite also do the same. Most Multigrade oils are ok as well. With the Muli some of us go out to 40:1 and still lube ok. Personal preference.
Cheers

Bruce and David,
Thanks for your advice. I'd read some of the older stuff on OME but had not seen that discussion on two stroke mix or grease for Blaxlands. It seems there is stil some debate. I must add that since I started using hald and half 50 grade and outboard oil I have not noticed any change in the deposits on my plugs or the side of the boat at the exhaust. I only use the boat rarely and then it may get a run of several hours straight.
This brings me to the question of water pump lubrication on th Blaxland for suc long runs. Is there a 'rule' about how often one should lubricate the saddle bearing?
Now that Aub Rose is no longer with us at least one of the 'horse's mouth's' cannot be consulted. I understand that neither Jack Forrest or Ray Patterson are either? Speaking of Aub, a friend has told me that all the parts etc from Aub's premises were sold for scrap?
Meanwhile, the discussion about the sump on a Blaxland makes me wonder if a small quantity of outboard gearbox oil (which contains an emulifier) wuld be a good idea to absorb any condensation?
I also have to admit the mention of not using a modern oil in a Simplex or Clae has also made me realise the value of OME. Having recently filled my Simplex twin (which has yet to be fitted to the boat) with a Penrite Marine 4 stroke oil I will now be aware of one reason why the gearbox might not do what I want.
Thanks again, Laurie |
