Yamaha - Main Nozzle - Carburetor Fuel Metering Component - 7CR-1495U-9A-00

Overview

Main nozzles are one of those parts you really notice when you’re pushing the engine. If it’s not delivering fuel properly, the motor can feel weak or hesitate under load. I’ve seen engines lose that strong top-end pull just from buildup or wear in this piece. When it’s right, the engine runs clean and pulls steady all the way through.

Key Features

• High-Throttle Fuel Delivery – Controls fuel flow through the carburetor at mid to full throttle.
• Precision Metering Design – Ensures accurate fuel distribution for consistent combustion.
• OEM Fit and Function – Built to factory specifications for proper installation and reliable operation.
• Supports Smooth Power Output – Helps maintain steady acceleration and eliminate hesitation.

Engine & Boat Compatibility

Designed for Yamaha outboard engines equipped with carbureted fuel systems that utilize a main nozzle for fuel delivery. Commonly used across a range of Yamaha outboards where accurate fuel metering is essential for performance under load.
