Interesting Paul as I have a 1936 Lister JP2M (marine version) in my boat. I bought it fully rebuilt by MPS, a father and son business near Poole, and drives a two foot prop via a modern PRM reduction gearbox and lives in its own walk through engine room. With new pistons, liners, injectors and pump its been totally reliable over the modest 2000 hours I've run it. Can't be quite so complimentary about its oil retention though
How wonderful. They are very special engines. Dad sometimes wonders if he should have stuck at it but he had spent a lot of money and he wanted to go boating.
Basford had a walk through engine room too. Fortunately, the 3 cylinder Lister was oil tight.
The overall design was intended to be along the lines of a BCN tug.
