Troubleshooting & FAQ

How do I know if this tune-up kit fits my engine?

This kit is designed for specific OMC, Johnson, and Evinrude outboard and sterndrive models that use ignition points systems. Cross-reference your original part number with those listed in our Part Number Matrix (OMC 0172525, 172525; GLM 72840; Sierra 18-5001) for the most accurate fitment.

What are the signs my ignition points and condenser need replacing?

Common symptoms include engine misfiring, difficulty starting, rough idling, poor acceleration, and decreased fuel efficiency. A visual inspection may reveal pitted, burned, or misaligned contact points.

What is the recommended replacement interval for this kit?

Replacement intervals depend on engine hours and operating conditions. It is best to consult your engine's service manual, but a general guideline is to inspect the points annually and replace them if they show signs of wear, pitting, or corrosion.

Is setting the point gap difficult?

Setting the point gap requires a feeler gauge and knowledge of your engine's precise specifications. While it can be performed by experienced DIY mechanics, we recommend consulting a service manual for the correct procedure. An incorrect gap can cause poor engine timing and performance issues.
