Sierra CDM Trigger Chrysler Force Sears & Gamefisher 2-Cylinder #18-99446
$169.74
$215.59
Sierra 18-99446 Ignition Timer Base
The Sierra 18-99446 is a replacement CDM (Capacitor Discharge Module) trigger for Chrysler, Force, Sears, and Gamefisher 2-cylinder outboards from 1996 to 1999, covering 40 and 50 HP models. The CDM trigger works alongside the ignition module to time spark delivery -- it reads flywheel position and sends the signal that tells the system when to fire. A worn or failed trigger on these engines typically causes no-spark conditions, misfires at specific RPM ranges, or an engine that starts cold but cuts out once it warms up.
This is a direct-fit replacement for the original CDM trigger. Three Chrysler/Force/US Marine part numbers interchange with this unit, so cross-reference your original part number against the list below before ordering.
Fits: 1996-1999 Chrysler, Force, Sears, and Gamefisher 2-cylinder, 40 and 50 HP
