Shire marine engines, supplied by Barrus, are developed for narrowboats, wide-beam boats, Dutch barges, river craft and inland commercial vessels. Their low-speed diesel operation, practical marinisation and compatibility with keel-cooled installations make them well suited to the demands of inland waterways.
For smaller working craft, the range includes the Shire 15, Shire 20, Shire 25 and Shire 30 workboat engines. The canal-boat collection extends through models such as the Shire 35, Shire 38, Shire 40, Shire 45 and Shire 50, giving builders and repower buyers several closely matched output options.
Larger wide-beam boats and barges can be powered by the Shire 60, Shire 65, Shire 70 or Shire 90. Choosing between these engines requires more than comparing boat length and horsepower; vessel displacement, hull form, propeller size, cruising speed and hydraulic or electrical accessory loads must also be considered.
Depending on the model, Shire canal boat engines may be supplied with twin alternators, calorifier connections, engine mounting systems, control panels and matched PRM marine gearboxes. Keel cooling is common on inland installations, but the required cooling area and pipework must be calculated for the engine’s output and operating conditions.
A quotation for a Shire marine engine for sale should confirm the exact model, gearbox and reduction ratio, cooling arrangement and alternator specification. It should also identify the control panel, wiring loom, mounts, exhaust components, optional equipment, warranty conditions, availability of genuine Barrus Shire parts, production lead time and delivery terms.
