Important Info

The application chart is just a general guide. Always include your engine model and serial numbers to be sure you receive the correct parts. If possible, also include the part number that's on your old part.

Ignition parts are not returnable. If you have any questions about troubleshooting or ordering the correct part, please contact us before ordering to avoid getting stuck with an incorrect part.

Warranty

CDI stators and switch boxes for Mercury/Mariner outboards and Sport Jets are covered for two years; triggers, coils, rectifiers, voltage regulators and harnesses are covered for one year.

Part numbers that begin with an R are remanufactured by CDI/Rapair and come with a 90-day warranty. Most "R" part numbers require that you send your old part in to be remanufactured.

Additional Parts Info

174-8778K1 (9 amp) & 174-9710K1 (16 amp) Stators 
These two stators are identical, except for the battery charging output. If you have a voltage regulator with "5279" in the part number, you can use 174-9710K1. If you only have a rectifier, you'll need to use 174-8778K1, unless you upgrade the rectifier to a CDI #194-5279 voltage regulator.

174-2075K1 (9 amp) & 174-2075K2 (16 amp) Stators 
These two stators are identical, except for the battery charging output. If you have a voltage regulator with "5279" in the part number, you can use 174-2075K2. If you only have a regular rectifier, you'll need to use 174-2075K1, unless you upgrade the rectifier to a CDI #194-5279 voltage regulator.
Note: These stators should only be used with CDM modules. If you have a switch box, use 174-8778K1 or 174-9710K1 instead.

Battery CD Ignition
Switch box part numbers 114-2986 and 114-4796 both come with new ignition coils, so there's no need to order them separately.

174-3175 & 174-3176 Stator Coils
Part number 174-3175 is $74.95 (Red Coil Only) and 174-3176 is $60.99 (Blue Coil Only).

134-6452 and 134-6454 Triggers 
Before ordering, be sure to check your linkage arm to see if it's straight or has a 90 degree hook in it, as shown in the picture. If it's straight, order 134-6452. If it does have a hook in it, order 134-6454. Note that the two parts are not interchangeable.
