Note the position of the old components. Replace the points and condensers for one cylinder at a time to avoid confusion.

Reinstall the flywheel, ensuring it is torqued correctly. Reconnect the battery and spark plug wires, then test the engine.

Troubleshooting & FAQ

How do I confirm this kit fits my specific engine model?

This kit is designed for the HP and year ranges listed in the Engine Compatibility table. Since specific model names are not listed, the best way to ensure fitment is to match the OEM part number (172522 or 0172522) from your engine's parts diagram or service manual.

What are the signs of failing ignition points or condensers?

Common symptoms include difficulty starting, engine misfires (especially at high speed), rough idling, backfiring, or a complete loss of spark. Visual inspection may show pitted or burned contact points.

How often should I replace these ignition parts?

Replacement intervals vary based on engine hours and operating conditions. As a general guideline, inspect the points every 100-200 hours or annually. Replace them if they show signs of wear, pitting, or if you are experiencing ignition problems.

Is setting the point gap difficult?

Setting the point gap requires a feeler gauge and careful adjustment. While it is a straightforward mechanical task, it is critical for engine timing and performance. If you are not familiar with the process, we recommend consulting a service manual or a professional marine mechanic.
