ENFIELD DRIVE LEGS (or Z-Drives/Sterndrives)
Originally manufactured in UK by the Royal Enfield Company (no longer in existance), taken over by Perkins Engines for a while, re-homed on the Isle of Wight, now manufactured in Birmingham (UK), main source of information, replacements and spares Chertsey Meads Marine (Surrey UK) 01932 564699.
Enfield Z Drives (or Z-Drives/Sterndrives) are very popular on the River, being easily lifted to clear or change the propeller or for mooring in shallow water.
Enfield model 130 Z Drives may be used with engines producing up to 140 lbsft (19 Kgm) maximum torque.
For petrol engines this is equal to approximately 130 HP. When diesel engines are used, the horse power may be 70-80 HP depending on the make and type of engine.
Maximum Torque 140 lb/ft at up to 5500rpm
Torque Calculation = HP x 5250/RPM at HP rating
Enfield Z Drives can only be used with engines which rotate anti-clockwise when viewed from aft.
Close or distance coupled to any inboard engine, the drive can take a propeller up to 14″ (355mm) diameter through reduction of 1.65:1. Propeller rotation is standard left hand; right hand is available for use with counter rotating twin installations.Swivel and non-swivel versions are available.
Enfield Z Drives Key Benefits
Swivel unit weighs only 104 lbs (47Kgs), and is ready to bolt direct to your transom. Inboard cranking means that the swivel model can lift athwartships for easy parking and maintenance, and lift 55° rearward to help avoid underwater obstructions.
The non-swivelling model embodies all the features of the swivel model with the exception of the athwartships parking mode, but has the advantage of a price and weight reduction to 90lbs (41 Kgs), and a greater lifting angle of 70°.
DIY users will find fitting simple and straightforward.
Accessories and Spares
We can supply a standard coupling kit from the engine flywheel to the Z Drive.
It is essential that these units are regularly serviced, correctly
set up and oil level maintained. Serious and expensive damage can
be caused by neglecting regular service. Any leaks from the
several oil seals will allow water to enter and oil to seep out.
This will cause corrosion of the internal parts, premature
failure of bearings and gears and possible total seizure.
Even the simple task of replacing a gear shift cable requires
exact setting up for correct performance.

of spares, seals, gaskets and all commonly required service
parts. Any items we do not have in stock can be obtained
