Yamaha - Fixed Injector - Fuel Delivery Component - 7DH-R4138-01-00

Overview

Fuel injectors are one of those parts where you notice problems fast—rough running, poor throttle response, or uneven performance. When a fixed injector isn’t doing its job, the engine just won’t feel right, especially under load. I’ve seen engines smooth out immediately after replacing a worn or clogged injector. When it’s working properly, fuel delivery stays consistent and the motor runs clean.

Key Features

• Consistent Fuel Delivery – Provides steady fuel flow for smooth and reliable engine operation.
• Precision Fuel Distribution – Designed to deliver the correct amount of fuel for balanced combustion.
• OEM Fit and Function – Matches factory specifications for proper installation and performance.
• Supports Clean Engine Operation – Helps reduce rough running and uneven power output.

Engine & Boat Compatibility

Designed for Yamaha outboard engines that utilize a fixed injector as part of the fuel delivery system. Commonly used across a range of Yamaha outboards where consistent and controlled fuel distribution is essential for engine performance.
