Marine Engine Data   

Home  +++  Narrow Boat "SIKA"  +++  EU Legislation  +++  CV

The information below may be useful for anyone seeking an engine for a 'traditional' narrow boat whether the engine is a new build classic, derated modern or a restored vintage. For an engine to be included it must have most of the following characteristics
Diesel or semi diesel
Low tick over rpm
Suitable hp at or below 1500 rpm
High torque
Robust construction
Heavy flywheel
Several points I would like to make -

More information and corrections will be added to the database over the coming months, as and when I get time.

The data is as accurate as can be but it should be noted that there may be variations. Some figures may be the continuous horse power rating, others not. The quoted horse power may have been chosen at a lower rpm figure more appropriate for narrow boat use, etc. etc. I even have manufactures data sheets for the same engine that quote different figures. In other words, the figures may not be 100% accurate but still remain a good guide in selection of an engine.

When (not if) anybody finds an error or has additional information, then I would be pleased if they would let me know by email at michael.clarke@skynet.be
