Twin Cylinder Engine Parts

31st July 2023

For sale from the estate of the late Pater Darby

Patterns – (all same engine)

Cylinder –4”x 4” stroke

Valve chest

Valve chest cover

Slide valve

Valve rod guide

Eccentric strap

Castings from above patterns.

Cylinders – 2 off (Machined)

Piston and rod assembly – 2 off (Machined)

Valve chest – 1 off ( Machined)

Cylinder cover – 1 off (Machined)

Slide valve –1 off

Crosshead assembly – 2 off machined ( one assembled with crank and con rod)

Crankshaft – 1 off machined (welded and appears straight)

Back columns – 2 off machined (assembled)

It is thought that this engine was a joint venture between Pater Darby and David King to replace the oversized engine in Myra. The parts available appear to be well made but are insufficient to build a twin engine, however, with a cut down crankshaft and remodelled bedplate a very nice and robust single 4” x 4” stroke engine could be constructed. A lot of time can be saved using these parts for anyone wishing to build an engine for a 25ft plus boat.

Offers around £150 with transport to be discussed.

Steam Outboard - Newcomen's atmospheric principle twin cylinder beam engine

7th May 2023

This experimental twin-cylinder atmospheric engine was built for the SBA Steam Outboard Competition in 2014, described in Funnel No 162.

During the competition, it was supplied with low pressure steam from a launch boiler but a domestic steam wallpaper stripper might produce enough steam to create a vacuum and turn it over.

Due to a house move the engine now needs a new home.

It is offered FREE of charge to a SBA member who would like to experiment with it.

1907-built Marine engine suitable for large launch or  steam narrowboat           

April 23 2021


I have for sale, in excellent condition, an attractive Finnish-built compound condensing marine engine suitable for a large launch by Tehtaat Lehtoniemi & Taipale in 1907, their no 197. 

Thought to be a rare survivor, the pictures show a substantially-built engine to suit a 30-40’ launch - or maybe a narrow boat -  with a number of interesting features. It has a large (LP) crosshead driven air pump, a comprehensive ten-point drip lubrication system all fed from one cylindrical glass-ended reservoir and, to British eyes, an unusual inbuilt ratchet-driven mechanical lubricator at the hp end.

The engine is owned by a private museum of technology in Germany. Before that, it belonged to a German company for about 40 years but any earlier history is not known to me

Approximate dimensions (located on the euro pallet):
length 120 cm
height 80 cm
width 70 cm

weight about 400 kg

We are looking for around 15,000 Euros  (ca £13k) but this is of course negotiable and there is the possibility of transport from Germany to the UK

If you have any questions, please contact Adam Golly (in English or German)  Email 


Boiler Suitable for 16' Boat


I have recently purchased my first steam boat project and am looking for a boiler, suitable for coal firing and preferably a VFT (although others considered) to drive a Taylor single engine (2.5" x 2.5" cylinder) in a 16' boat.

Before I dive in and start building a boiler, I thought it just worth asking on here as you never know what people have tucked away!

Not entirely sure what I'm after as there is still some freedom in the boat to move things about, but if you've anything that sounds like it may be of use please get in touch to discuss!


For Sale

Four Cylinder Launch Engine
(Under construction)


Bob McMillan’s partially built engine designed by Trefor Milns is for sale. He and Trefor were both building them at the same time.

We have all the casting patterns, the drawings etc. Bob had intended this engine to power his 'next boat' which was supposed to be about 36' long.

The engine is a 4 cylinder triple expansion and has already had a substantial amount of work done to it. Rough dimensions are L 100cm, W 50cm, H 75cm.

All sensible offer will be considered.
