Installation Notes

1. Disconnect the battery and wait 10 minutes to discharge any residual voltage in the ignition system.
2. Locate the original CDI module, typically mounted near the powerhead or under the flywheel cover.
3. Label and disconnect all wiring harness connectors from the old module to ensure correct reassembly.
4. Remove mounting hardware and lift out the failed module.
5. Position the new module in the same orientation and secure using factory mounting points.
6. Reconnect all wiring harness connectors, ensuring each plug is fully seated and locked.
7. Inspect connector pins for corrosion or damage; clean or replace as needed.
8. Reinstall any covers or cowling removed during disassembly.
9. Reconnect the battery and perform a spark test to confirm ignition output.
10. Start the engine and verify smooth idle and throttle response across the RPM range.

Troubleshooting & FAQ

How do I know if my CDI module has failed?

Common symptoms include hard starting, intermittent misfires, loss of power at high RPM, or complete failure to spark. Use a spark tester to confirm whether the ignition coil is receiving signal from the CDI before replacing.

Will this module work if my engine has an RPM limiter?

No. This module is designed for 2-cylinder engines from 1977–1984 that do not require an RPM limiter. If your engine uses an RPM-limiting CDI, you must source the appropriate version.

Can I install this module without special tools?

Yes. Installation requires basic hand tools (screwdrivers, wrenches) and a spark tester. No specialized diagnostic equipment is necessary for a straightforward swap.

What is the difference between this aftermarket module and the OEM part?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

How often should the CDI module be replaced?

CDI modules typically last many years under normal conditions. Replace only when diagnostic testing confirms failure, or if you experience persistent ignition issues that cannot be traced to coils, stator, or wiring.

Will this fit both manual-start and electric-start models?

Yes, as long as your engine is a 2-cylinder Johnson Evinrude from 1977–1984 within the 4–60 HP range and does not use an RPM limiter. Starting method does not affect CDI compatibility.

What shipping speed and cost can I expect?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

What warranty and return options are available?
