ELECTRICAL PARTS INDEX

Rapair/CDI Electronics has grown to be THE source for quality electronic ignition parts for all makes of US outboard motors. Now supplying some of the OEM manufacturers with selected components. Some components of the outboard electrical system are not available from CDI, in this case I have listed the FACTORY part in its place in the shopping cart.

The next-to-last page of this listing has the 1967 thru 1972 battery CD ignition models; the last page is a recap of all models from 1971 thru 1984. Evinrude Johnson models after 1984 became pretty complex in that components changed yearly, sometimes from model to model in the same horsepower range. If you have any questions, please call me and I will help you sort it out!

Magnets come off your 90° 35-amp flywheel? Here's a fix!

THE POWERPACK is the portion of the ignition system that stores electrical energy produced by the stator (or steps up battery voltage and stores it in older systems) and distributes this power to the ignition coils. The complexity of this circuitry causes numerous failure modes, generally the large storage capacitor shorts out.

TROUBLESHOOTING TIP. All electric start motors have a "stop" or "kill" circuit that carries all the primary power thru the wiring harness and keyswitch as well as the emergency stop switch on newer models. Shorting of this high voltage circuit on magneto energized CD systems many times is the source of misses, intermittent spark, weak spark and NO spark. An easy test (and the FIRST test I run) is to disconnect the stop circuit at the powerpack plug-in or screw terminal. This wire will be black with a yellow stripe on all modern motors. This will isolate the harness, etc. and allow you to see if the motor's system is functional.

CAUTION!! The motor will not shut off with the key during this test. You will have to choke it to shut it down, and it could start from your turning the flywheel by hand. I do not recommend you run the motor other than testing with this wire disconnected.
