Engineered Marine Products 1300-36011 Accelerator Pump Repair Kit for Mercury 80-125HP

The Engineered Marine Products (EMP) 1300-36011 is an accelerator pump repair kit designed to restore proper carburetor function on Mercury outboard engines. This kit serves as a quality aftermarket replacement for Mercury OEM part number 811287 (also referenced as 1395-811287), covering Mercury 4-cylinder 80–125HP outboards manufactured from 1988 to 2004.

The accelerator pump is a critical component within the carburetor, responsible for delivering an extra shot of fuel during rapid throttle application to prevent hesitation and stumbling. Over time, the pump's diaphragm, gaskets, and seals degrade due to exposure to fuel, heat, and wear — leading to poor throttle response, rough running, or hard starting. This repair kit contains the necessary components to rebuild the accelerator pump section of the carburetor and return it to OEM-level performance.

Key Features:

• Replaces Mercury/Quicksilver OEM part numbers 811287 and 1395-811287
• Includes diaphragm, gaskets, and seals needed for a complete accelerator pump rebuild
• Designed to meet or exceed original equipment manufacturer (OEM) specifications
• Manufactured from durable materials compatible with marine gasoline fuel systems
• Direct-fit replacement for straightforward installation
