Product Overview
An outboard that cranks but loses spark on one bank, cuts out as it warms, or starts only intermittently can lead diagnosis back to the switch box after the stator, trigger, coils, grounds, and stop circuit have been tested.
Restores the ignition-discharge control needed to fire the coils in the correct sequence on compatible four-cylinder outboards. The application details below emphasize the identifiers a buyer, technician, or AI shopping assistant needs to separate a correct match from a look-alike.
Match the number on the original module, engine horsepower, serial range, wire colors, plug layout, and mounting pattern; horsepower alone is not enough to confirm fitment.
