Engineered Marine Products 300-02811 Distributor Rotor

The Engineered Marine Products 300-02811 is an ignition distributor rotor for marine engines. It sits inside the distributor cap and turns with the distributor shaft. As the rotor tip passes each cap terminal, it carries the high-voltage pulse from the ignition coil to the matching cylinder. That pulse ignites the fuel-air mixture.

Key Points:

• Distributor rotor that routes coil voltage to each cylinder in firing order
• Works with the distributor cap as part of the ignition system
• Sold individually as a single replacement part

A worn or damaged rotor can cause misfires and rough running. Replacing it is a common part of a tune-up.
