Introduction

Vetus mechanical remote engine controls are designed to operate both the gearbox and the fuel pump (throttle) via a single lever. This ensures efficient and integrated control of marine engines.

Installation

2.1 Pull-Push Cables on the Mechanism

The mechanism is designed for direct control of the throttle (accelerator) and the gearbox (gear change). The control can be either 'push' or 'pull' for both functions, with specific configurations for forward and reverse gear engagement.

Important: Always connect the cables to the mechanism first. Connection to the gearbox and throttle should only be made after the entire remote control mechanism is installed. Before connecting cables, remove the lever and housing parts as shown in the diagrams.

The mechanism is compatible with Vetus and Morse 33C cable types, as well as OS (OMC) and KM (Mercury) cable types. Mounting holes are numbered to correspond with these cable types.

Ensure both functions of the mechanism are in neutral before connecting cables. Specific cable connection diagrams for throttle and gearbox are provided on page 14.

Cable Installation Guidelines:

• Ensure adequate total cable length.
• Minimize cable bends and use the largest possible bending radius (minimum 500 mm).
• Clamp cables at regular intervals (every 60 cm).
• Avoid installing cables near heat sources like exhaust systems.
• Prevent cable abrasion.
• After installation, check that cables move freely without resistance.

2.2 Pull-Push Cables on the Engine

Connect the cables to the gearbox and throttle as specified by the engine supplier. Verify that the engine throttle lever reaches its full travel and that the gearbox operates correctly.

2.3 Neutral Switch

The mechanism includes a neutral switch that prevents the engine from starting if the gearbox is engaged. Connect the switch as shown in the electrical diagrams on page 15 if this feature is utilized.

2.4 Multiple Remote Controls

For engines with multiple remote controls, differential devices are required to connect the controls, allowing independent operation from two locations. Two differential devices are needed per engine (one for gearbox, one for throttle).

2.5 Housing and Lever

When selecting the mounting location for the housing and lever, consider the lever's maximum swing and the overall mechanism dimensions.

Mounting Instructions

Top Mounting: Use the supplied drill pattern to mark holes and the opening. Brackets on part A serve as mounting brackets. Drill holes, saw opening, apply spacer, and assemble with M5 bolts. Grease mechanism axle B and mount lever. Secure with M10 bolt and Loctite 243. Check cable routing.

Side Mounting: Requires at least 180 mm clearance behind the bulkhead. Use the drill pattern to mark holes and opening. Drill holes, saw opening, apply sealant A, attach mechanism B to plate, and secure to bulkhead with bolts. Grease mechanism axle and mount lever. Secure with M10 bolt and Loctite 243. Check cable routing.

Adjustments

Screw 1 allows adjustment of the throttle mechanism friction based on the throttle's counter-pressure.

Control

Button 2 can disengage the gearbox, allowing only throttle control (e.g., for starting or warming up the engine). The button automatically returns to its original position when the lever is moved to neutral, making the remote control ready for normal use.

Maintenance

• Clean the lever and housing with freshwater as needed.
• Regularly check the mechanism for loose parts and wear on moving components.
• Apply a water-resistant lubricant to moving parts routinely.
• Regularly inspect cables and connections for wear and corrosion.

Electrical Diagrams

Page 15 provides electrical circuit diagrams for various configurations, including single and dual command stations, with and without restart protection, and details on starter switches, relays, neutral switches, charging lights, and alternators.

Differential Device

Page 15 also illustrates the differential device used for connecting multiple remote controls to a single engine, specifying its use for both throttle and gearbox.
