Single Cylinder Wilkinson Launch Engine

9 September 2021

This modern launch engine with a well-worked out lubrication system for clean, quiet running was designed and built by Sam Wilkinson to suit an 18-ft launch and modified by Ian McAlpine. It runs well, has clocked up very few hours and to all intents and purposes is practically new.

It is a slide valve single of 65-mm bore x 75-mm stroke (approx 3 x 2 1/2 inches) with slip-eccentric reversing gear, pumped lubrication to valve-chest, cylinder and crosshead/small end as well as wick-feed via nylon tubes to other bearings. It comes complete with a belt-driven slow-running pumpset (feed + condensate) also built by Sam.

Approx overall dimensions (excluding pumpset) are:- Height: 19-ins above bearers.

Length: bedplate 8 1/2-ins.

Over couplings 13-ins.

Width: bedplate 11 1/4-ins.

Overall 13-ins.

There is also a propeller made to match the engine, 16 x 23”  (LH) and a second propeller 15 x 24-ins (RH).

Large single cylinder marine engine

18 August 2021

We have been asked to advertise an interesting over-square 6” bore x 5” stroke single cylinder launch engine built in the USA by Scripps Foundry & Machine works of Fredericksburg, Texas.

This engine was probably built in the 1970s and the pictures show it to be designed along classic lines and exhibiting features that nod toward early 20th century US Navy pinnace engine practice, including the columnar frame and pattern of reversing quadrant. It has Stephenson’s link reversing and a crosshead-driven feed pump. There is with it what appears to be an exhaust feed water heat exchanger.

The engine, unused for nearly 30 years and showing exterior rust, is in need of complete restoration. It is being sold by its late owner’s son-in-law who has found a number of letters from foundry owner Robert Scripps indicating that this engine was imported to Britain in 1994 for use in a steam narrowboat project which never came to fruition. It, or a similar single, had possibly seen action in a small stern wheeler in the US.

The engine is currently stored near Louth, Lincolnshire and since this is a large and heavy engine  - it stands over three feet high - collection would require an appropriate hoist and logistics.

Offers are invited in the region of £1200 – but talk to me!
