Yamaha - Main Nozzle - Carburetor Fuel Metering Component - 7CR-1495U-6B-00

Overview

Main nozzles are one of those parts you really notice when you’re pushing the engine. If it’s not flowing right, the motor can feel flat or struggle to pull under load. I’ve seen engines lose top-end performance just from a partially clogged nozzle. When it’s clean and correct, the engine runs strong and steady through the throttle range.

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 specs for proper installation and reliable performance.
• Supports Smooth Power Output – Helps maintain steady acceleration and strong engine response.

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.
