Package Contents

Installation Guide

1. Ensure the engine is turned off and cooled completely.
2. Disconnect the battery to prevent accidental starting.
3. Loosen the alternator pivot bolt just enough to allow slight movement; also loosen any adjuster-plate or tensioner bolts.
4. Identify the belt routing path around all relevant pulleys.
5. Remove the old belt by swiveling the alternator or tensioner to relieve tension, then slip the belt off the pulleys.
6. Inspect pulley grooves for wear, rust, or corrosion; clean if needed.
7. Route the new belt following the same pulley path, ensuring it is properly seated in all V-grooves.
8. Tension the belt: Swivel the alternator away from the engine to create proper tension. A correctly tensioned V-belt should deflect about 1 cm (½") under moderate thumb pressure on the longest span.
9. Tighten all bolts: securely fasten the adjuster-plate bolt first, then the main pivot bolt to factory torque specifications.
10. Reconnect the battery.
11. Start the engine and observe the belt tracking to ensure it is centered in the grooves and running smoothly.
12. Shut down the engine and recheck tension after a short run-in period, as new belts may stretch slightly.

Troubleshooting & FAQ

How do I confirm this timing belt fits my Yamaha 4.2L V6 engine?
The best way to ensure compatibility is to verify your engine's model and year against the "Compatible Engine Models" table on this page. Cross-referencing the OEM part number (6CB-W4624-00-00) with your service manual or current part is also a reliable method.

What are the signs that my timing belt needs replacement?
Common signs of a failing timing belt include visible fraying, cracking, glazing, or missing teeth on the belt itself. You might also hear a ticking or slapping noise from the engine cowling, or experience poor engine performance, misfires, or difficulty starting.

How often should a Yamaha outboard timing belt be replaced?
As a critical maintenance item, it's recommended to follow the service interval specified in your Yamaha owner's manual. A general guideline for many outboards is every 1000 hours or 5 years, whichever comes first. However, always defer to your official service documentation.

Does this kit include everything needed for the replacement?
Yes, this is a complete kit that provides both the high-quality timing belt and the necessary set of rotor bolts. This ensures you have all the required components for a proper and secure installation.
