The ENFIELD "Z-DRIVE" transom unit is a transom-mounted drive unit designed for marine applications, incorporating a reverse and reduction gear. It is adaptable to either petrol or diesel engines within its power capacity. The standard mounting plate is configured for a transom raked aft at 12° to the vertical, with adaptor blocks available for different transom angles.
The Z-DRIVE system provides a direct coupling to an engine without requiring a separate gearbox. Power is transmitted from the engine via a flexible rubber-metal coupling to the drive unit input shaft. Two constant-velocity universal joints then transfer power to the top bevel gears, and from there, through a floating mainshaft, to the gearshift bevels on the propeller shaft.
An external lever on the port side of the unit controls the gear change through an internal linkage to a sliding dog clutch on the propeller shaft. Gear positions include forward, neutral, and reverse. A lock automatically engages in the astern gear position to prevent the unit from kicking up under reverse propeller thrust. The external gear change lever is designed for a single-lever control cable system, featuring quick-release cable fittings. The system accommodates alternative cable strokes by selecting different anchoring holes on the control head. The engine should always be started in neutral, and gear shifting should only occur when the engine is idling.
The standard propeller rotation is left-hand (anti-clockwise when looking forward in forward gear). The unit can also be configured for opposite rotation, allowing for contra-rotating twin units. The Z-DRIVE is designed for engines that rotate anti-clockwise when viewed from aft. Clockwise rotating engines can be used, provided the manufacturer is informed during ordering.
Steering is managed by a tiller arm, which can be adapted for either wire rope and pulley systems or proprietary push-pull systems. The special steering linkage does not need to be disconnected when swivelling the drive unit to the parked position or when tilting it.
To park the unit, engage astern gear just before stopping the engine to ensure the drive does not slip off the reverse catch bar. Pull the plunger release cable to withdraw the locating plunger. Turning the winding handle in the Z-DRIVE socket will cause the body to swing sideways to starboard (due to a stop plate on the swivel plate) until the plunger re-engages. The drive is then parked and should be supported with ropes or blocks for trailing.
If the Power Trim system is correctly assembled, pressing the switch down trims the body inwards until the rams are completely closed. Trimming out is achieved by pressing the switch upwards. While underway, the gauge will show a reading up to 600 p.s.i., with 1000 p.s.i. indicating end of travel. Continuous operation beyond this point can lead to overheated wiring and damage. For parking, it is recommended to leave Power Trim models with the bodies down, ensuring the rams are fully closed to prevent marine growth on the piston rods.
