What’s Inside the Sierra 18-5260 Kit?

Precision is vital when it comes to ignition timing. This “minor” tune-up kit includes the three critical wear items needed to restore your spark:

• 18-5345 Condenser: Built to withstand voltage spikes and prevent point pitting.

• 18-5403 Rotor: Balanced and durable to ensure accurate distribution of high-voltage current to the spark plug wires.

Wide Compatibility and OEM Cross-Reference

One of the reasons the Sierra 18-5260 is a bestseller is its versatility. It serves as a direct replacement for several major manufacturers, meeting or exceeding original equipment specifications. It is compatible with engines from Mercruiser, Volvo Penta, OMC, Chris Craft, and Crusader.

Installation Tips for Boat Owners

When installing your new kit, always ensure the battery is disconnected. Since this is for a screw-cap distributor, be careful not to overtighten the cap screws, as the plastic housings can become brittle over time. Always check your point gap according to your specific engine manual to ensure the dwell angle is set correctly for peak V8 performance.
