Product Details
✓FITMENT - For Mercury/Mariner 30-300HP and Force 40-120HP 2-stroke outboards on the 4-pin CDM system: 2, 3, 4 and 6-cylinder engines, one module per cylinder. One module per pack, order one per cylinder. Match model, serial and old stamp.
✓REPLACES - Replaces Mercury/Mariner 827509A10, superseding 827509A4 and covering 827509A1, A3, A7, A8, A9 and T7. A7 supersedes to T7, so match each cylinder. Crosses CDI 114-7509, now Sierra 18-99161, Mallory 9-23202. Not genuine Mercury.
✓BUILD - Per module: 4-pin sealed connector, epoxy-sealed housing, integral coil with one spark plug boot, 12V DC, bolt-on with two mounts. One module per pack. Mounting hardware and spark plug wires are not included.
✓FUNCTION - Each CDM switches the discharge and fires one cylinder. Resolves no spark on one cylinder, misfire that clears on restart, rough idle, sudden stall and dying at higher rpm when the module is the fault. Check stator, trigger, stop circuit.
✓BEFORE ORDERING - Not for 6-pin switch boxes like 339-5445, not for 3-pin early CDM/TPI, not for 4-stroke EFI with individual coils. Count 4 pins. A10 and T7 are not interchangeable in every cylinder position, so match each stamp. Disconnect battery.
