Product Description

647-14342-42-00
Jet, Pilot (# 84), Yamaha,
For Outboard: Yamaha 40

Features:
1. Precise Fuel Flow Control: The main jet controls fuel flow by having a specifically calibrated orifice that allows a precise amount of fuel to pass through at higher speeds.
2. Durable Construction: Made from corrosion-resistant materials, the main jet is designed to withstand continuous fuel exposure and the high temperatures of the engine.
3. Calibrated Design: Each main jet is finely tuned to suit specific engine needs, ensuring consistent fuel delivery and supporting peak performance at mid-to-high speeds.
4. Optimized Fuel Consumption: By controlling the fuel flow accurately, the main jet helps maintain an optimal air-fuel mixture, reducing the risk of excessive fuel consumption.

Functions:
1. Fuel Delivery at Higher RPMs: The main jet regulates fuel flow during mid-to-high RPMs, delivering the additional fuel needed for higher power output as the engine speed increases.
2. Ensuring Proper Air-Fuel Mixture: Working in conjunction with the carburetor, the main jet ensures that the engine receives the right air-fuel ratio for efficient combustion at high speeds, promoting power and fuel efficiency.
3. Supporting Throttle Response: By supplying consistent fuel flow, the main jet enhances throttle response, allowing the engine to smoothly accelerate and maintain speed without lag.

Maintenance Tips:
1. Regular Cleaning: The main jet can become clogged over time due to fuel residues or debris. Regular cleaning of the carburetor, including the main jet, helps maintain smooth fuel flow.
2. Use High-Quality Fuel: To minimize clogging, use high-quality fuel, as impurities in low-grade fuels can contribute to buildup within the jet.
3. Periodic Inspection: During routine maintenance, inspect the main jet for signs of wear, corrosion, or blockages. Cleaning or replacing a worn jet helps maintain consistent engine performance.
4. Seasonal Fuel Stabilization: If storing the motor for extended periods, add a fuel stabilizer to prevent deposits in the fuel system. This helps keep the main jet free from residue buildup.

Common Signs of Main Nozzle:
1. Clogging: Over time, fuel residues and impurities can clog the main jet, leading to reduced fuel flow, poor throttle response, and reduced power, particularly at higher speeds.
2. Wear from Abrasive Particles: Small contaminants in the fuel can wear down the jet orifice, affecting its accuracy and reducing fuel efficiency and performance.
3. Corrosion: Though made from corrosion-resistant materials, long-term exposure to ethanol-blended fuels or saltwater environments may lead to corrosion, compromising fuel flow.
4. Inconsistent Performance at High RPMs: If the engine struggles to reach higher RPMs or exhibits poor performance under load, it could be due to an issue with the main jet, such as blockage or incorrect sizing.
