QUADRUPLE ENGINE INSTALLATION

SYSTEM STRUCTURE AND OUTLINE

  1. Remote Control box

On the Quadruple Engine Installation of DBW (Drive by Wire) models, all engines can be controlled by a twin lever remote control box.

  • The port remote control lever controls both port engine and port center engine.

  • The starboard remote control lever controls both starboard engine and starboard center engine.

  1. BCM (Boat Control Module)

Necessary BCMs:

  • One BCM for the port and port center engines.

  • Another BCM for the starboard and starboard center engines So that two BCMs are required for the quadruple engine installation with single station on a boat.

Also four BCMs are required for the quadruple engine installation with dual station on a boat.

While communicating the BCM each other, the BCM controls to prevent mismatches between two engine groups that are the port and port center engines and the starboard and starboard center engines.

  • On the dual station:
    Neither main BCM for the PORT engine group nor sub-BCM for the STBD engine group communicate each other.

Similarly, neither main BCM for the STBD engine group nor sub BCM for the PORT engine group communicate each other.

About BCM

The BCM for quadruple engine installation (p/no.: 36770-98J20) which has communication function with other BCM is strictly designed for that system.

The BCM (p/no.: 36770-98J11) is for single, dual and triple engine installations.

Use the BCM and its quantity appropriate to the system.

The system doesn’t work correctly when the incorrect BCM is used.

  • When the BCM for quadruple engine installation (P/No.: 36770-98J20) is used on single, dual and triple engine installations, system error is indicated due to no communication can be made with other BCM. The system error indication is turning on the LED diagnostic lamp in the switch panel and beeping the buzzer.

In this condition, there are no functions of changing station and throttle only.

  • In reverse, when the BCM (P/No.: 36770-98J11) for single, dual and triple engine installations is used on quadruple engine installation, there is a possibility of mismatch to the functions of “changing station” and “throttle only” due to no communication between two port side engine group and two starboard side engine one.

Example of mismatches;

(1) When changing station to the 2nd one from the 1st one at the starboard and starboard center engine group, they can be controlled by the 2nd station but can’t do to the port and port center engine group.

(2) When selecting the throttle only function at the starboard and starboard center engine group, they can be controlled throttle only but can’t do to the port and port center engine group.

3. Sub-Battery Cable

A sub-battery cable is required for each engine groups that are two port-side engines and two starboardside ones.

  • One sub-battery cable for the group of port and port center engines.

  • Another sub-battery cable for the group of starboard and starboard center engines.

4. Battery

  • One battery is required for each of the engines in the case of quadruple engine installation as the same manner for the other multiple engine installation.

  • Connect the negative battery terminals of all batteries together to maintain the BCM power source in the case of multiple engine installation.

  • Use a negative cable mentioned above with AWG 2 or larger thickness (lower gauge number) to connect the negative terminals of each engine batteries.

In multiple-motor installation, to maintain the BCM power source, all of the negative battery terminals should be connected together.

Failure to follow these instructions may cause the wire to overheat and a fire may result. Use a cable with AWG (American Wire Gauge) number 2 or larger thickness (lower gauge number) to connect the negative battery terminal.

5. System Wiring

Refer to page 57, 59 for the wiring of the system.

6. Electronic Calibration for the System

The electronic calibration is the same way as for the dual engine installation with single station and the dual engine installation with dual station. In other words, the electronic calibration for quadruple engine installation is equal in two times of that for dual engine installation.

  • Calibrate the group of port and port center engines first then the group of starboard and starboard center engines.

  • Or calibrate the group of starboard and starboard center engines first then the group of port and port center engines.
