1963 Lister JS3M

Lister JS3M - Year of Manufacture 1963

This Lister JS3M is a very rare piece of Lister engineering and is a later developement of the Lister JP3M. This model included various upgrades, it still retains the compression change over valves as per the JP's but has the addition of oil feed pipework to the valve rocker shafts so no more daily greasing is needed and the engine also has an increased maximum rpm of 1500 instead of the JP's 1200rpm.

The JS model was only ever produced as a 3 cylinder and is rare even in industrial guise so this marine variant is like hens teeth.

This engine produces 43.5hp @ 1500rpm, This engine is a genuine marine unit and was complete with the orignal lister fitted Blackstone 2:1 ratio gearbox and raised hand start. This engine has now undergone complete restoration which included conversion to electric start and the replacement of the mechanical Blackstone gearbox with a modern PRM 260 2:1 ratio gearbox.
