This timing belt kit is specifically used on select Yamaha XF425 and XF450 XTO Offshore outboards. These engines use different timing-system components than many earlier Yamaha F-series outboards.
Always verify the complete Yamaha engine model before ordering. XF425 and XF450 model suffixes can identify different engine configurations.
Confirm that the application calls for Yamaha 6GR-W4624-00-00.
Matching Yamaha Timing Belt Tensioner
The timing belt tensioner should be inspected whenever the timing belt is serviced. The Yamaha tensioner below is used on select XF425 and XF450 applications covered by this belt kit.
Yamaha OEM Timing Belt Tensioner - 6P2-11590-05-00
Genuine Yamaha OEM timing belt tensioner for compatible Yamaha XF425 and XF450 XTO applications, along with several other Yamaha four-stroke engine families.
If the tensioner shows bearing noise, binding, poor belt control or excessive wear, replace it while the timing system is already apart.
What the Timing Belt Does
The timing belt keeps the crankshaft and camshafts synchronized so the engine's valves operate at the correct point in the combustion cycle. Accurate valve timing is essential for proper engine performance.
On high-output Yamaha XTO engines, the timing system operates under significant load. The belt, tensioner and related timing components should therefore be inspected carefully during scheduled service.
Why Are Rotor Bolts Included?
This Yamaha kit includes the timing belt and rotor bolts required as part of the applicable timing-system service procedure.
Supplying the bolts together with the belt helps ensure the correct service hardware is available when the timing assembly is disassembled.
Common Signs the Timing System Needs Service
- Timing belt has reached its scheduled service interval
- Visible cracking or deterioration
- Frayed or damaged belt edges
- Missing or damaged belt teeth
- Oil or fluid contamination on the belt
- Abnormal noise from the timing-system area
- Loose or inconsistent belt tension
- Worn or noisy timing belt tensioner
Why Inspect the Tensioner During Belt Replacement?
A new timing belt depends on the tensioner to maintain proper belt control. A worn tensioner can allow excessive movement, incorrect tension or premature belt wear.
Whenever replacing the 6GR-W4624-00-00 timing belt, inspect the Yamaha 6P2-11590-05-00 tensioner and related timing components before reassembly.
