Product Overview
Replacement CDM ignition coil / capacitor discharge module for selected Mercury and Mariner outboard engines using a compatible CDM-style ignition system.
Designed for selected 30HP, 40HP, 50HP, 55HP, and 60HP 2-stroke outboard applications, this unit combines ignition-module and secondary ignition-coil functions in a single assembly.
The unit features approximately 73.7mm / 2.90 in mounting-hole spacing and a 152.4mm / 6 in ignition wire for additional fitment verification.
Before ordering, verify the engine horsepower, model/serial number, original CDM part number, mounting dimensions, electrical connections, and original module appearance.
Product Compatibility
| Make | Engine | Engine Type | Fitment Notes |
|---|---|---|---|
| Mercury / Mariner | 30HP | 2-Stroke | Selected CDM ignition applications |
| Mercury / Mariner | 40HP | 2-Stroke | Verify engine serial number and original CDM |
| Mercury / Mariner | 50HP | 2-Stroke | Selected CDM-equipped models |
| Mercury / Mariner | 55HP | 2-Stroke | Verify OEM number |
| Mercury / Mariner | 60HP | 2-Stroke | Selected compatible applications |
Fitment varies by year, cylinder configuration, and engine serial number. Horsepower alone should not be used to confirm compatibility.

Domande frequenti sulla compatibilità
Questa parte è compatibile con il mio modello e anno specifici?
This CDM ignition coil is intended for selected Mercury/Mariner 30HP, 40HP, 50HP, 55HP, and 60HP 2-stroke outboards using a compatible CDM ignition system.
Mercury used different ignition components across engine years and serial ranges, so horsepower alone does not confirm fitment.
Devo corrispondere al numero di parte OEM?
Yes. Matching the original CDM part number is strongly recommended.
Related CDM references include 827509A10, 827509T7, 827509A7, 827509A4, and other numbers within the same ignition-module family.
You should also compare the mounting dimensions, connectors, ignition lead, and physical appearance.
A quali modelli o situazioni non si adatta questa parte?
Do not assume compatibility with:
Every Mercury 30HP–60HP outboard
Mercury 4-stroke engines based only on horsepower
Engines using a conventional standalone ignition coil rather than this CDM design
Modules with different electrical connections
Applications with different mounting-hole spacing
Engines requiring a different OEM CDM number
The engine serial number and original ignition module provide more reliable fitment information than horsepower alone.
Cosa dovrei controllare prima di ordinare?
Confirm:
Mercury / Mariner engine model
Engine horsepower
2-stroke engine configuration
Engine serial number
Original CDM/OEM number
Approx. 73.7mm mounting-hole spacing
Approx. 152.4mm ignition wire length
Electrical connector configuration
High-tension lead connection
Original CDM appearance
Compare the product photos with the original module before purchase.
