Description
Product Introduction & Engineering Value
A main engine control system depends on hundreds of signal decisions happening correctly every second. When a central PCB begins failing, symptoms can appear as communication faults, abnormal indications, or unexpected control behavior. The NABCO MCA-901-11 provides maintenance teams with a board-level replacement option for existing NABCO engine control installations.
This PCB card is associated with NABCO main engine control applications and is identified by part number 885 73748388. Because these systems often remain in service for many years, accurate identification, revision verification, and controlled replacement procedures are essential before returning equipment to operation.

Field Application & The “Trench” Experience
A container vessel operating with an older NABCO main engine remote control system began experiencing irregular control indications during maneuvering tests. The engine hardware was operating normally, but the automation cabinet showed intermittent behavior that could not be traced to field devices.
The maintenance team isolated the issue through signal tracing and cabinet inspection. The suspected failure was narrowed down to the main PCB assembly. After confirming the installed board markings, the team replaced the failed unit with a NABCO MCA-901-11 matching the 885 73748388 reference.
Following installation, wiring verification, and operational testing, the vessel returned to normal service without replacing the complete engine control system.
Typical engineering applications:
- Main engine remote control system restoration
- Marine propulsion automation spare management
- Legacy NABCO control cabinet maintenance
- Shipyard overhaul projects requiring original PCB assemblies

Transparency SOP: QA & Testing
A main control PCB requires careful verification before installation into a vessel control system.
Inspection workflow:
1. Identification review
- Confirm NABCO label information.
- Verify MCA-901-11 model number.
- Match part number 885 73748388.
2. Physical inspection
- Examine PCB surface condition.
- Check connectors and edge contacts.
- Inspect solder joints and component areas.
3. Electrical assessment
- Perform applicable continuity and resistance checks.
- Inspect power sections and critical circuits.
- Compare against known-good references when available.
4. Spare preparation
- Apply ESD-safe packaging.
- Record inspection results.
- Maintain inventory traceability.
The Veteran’s Tech Trap Guide
⚠️ Do not confuse MCA-901-11 with MCA-901-11A.
Related listings show both designations in circulation. Always confirm the exact installed model and documentation before replacement.
⚠️ Verify the complete part number.
The difference between 885 73748388 and nearby MCA-series references is important. A physically similar board may not perform the same control function.
⚠️ PRO TIP: Capture cabinet wiring before removal.
Main control boards often connect to multiple signal groups. A clear record of connector locations reduces commissioning mistakes.
⚠️ Do not skip functional testing.
A PCB replacement should be validated through the actual engine control sequence, not only by confirming power-up.
