Engineered Marine Products 300-02811 Distributor Rotor for GM Marine Engines

The Engineered Marine Products 300-02811 is a replacement distributor rotor designed for marine applications with GM engines equipped with Delco ignition systems. This component plays a critical role in your engine's ignition system by transferring high-voltage electrical current from the ignition coil to the spark plug terminals.

Key Features:

• Direct replacement rotor for GM 4-cylinder (120-140 HP) and 6-cylinder (165 HP) marine engines
• Compatible with 1968-1990 GM engines equipped with Delco ignition distributors
• Designed to withstand the harsh marine environment
• Ensures proper voltage transfer for reliable engine ignition
• Quality engineered construction for long service life

Application:

• Fits: 1968-1990 GM 4-cylinder engines (120-140 HP)
• Fits: 1968-1990 GM 6-cylinder engines (165 HP)
• Requires: Delco ignition system

The rotor rotates inside the distributor cap and is directly connected to the ignition coil. As the rotor tip passes each contact point, a high-voltage pulse crosses from the coil through the rotor to the appropriate cylinder, igniting the fuel-air mixture. Regular replacement of the distributor rotor is essential for maintaining reliable engine performance and starting.
