Currently available is this 1957 built Lister JP3. 35hp @ 1200rpm, This engine is an example of a Marine Power Services marine converted Lister JP3. Starting its life as an industrial version this engine is undergoing a total restoration and conversion to marine specification.

Another part of this conversion is the fitting of electric start, a Jabsco water pump and thermostatic temperature control, along with a full set of new wet manifolds as fitted to genuine marine Lister JP's, this includes the water cooled exhaust manifold, drum silencer and water outlet rail.

This engine is not just a standard industrial engine with the minimum plate mounted adaption to fit in a boat. This engine has been fully converted to the marine spec as Lister intended.
