What Does the Timing Belt Do?
The timing belt is a critical component of a Yamaha 4-stroke engine.
It synchronises the movement of the camshaft, valves and pistons, allowing the engine's valve timing to operate correctly.
Yamaha describes the timing belt as a vital component of its 4-stroke engines and specifies replacement according to the appropriate service schedule. Yamaha Motor Europe
Important – Timing Belt Replacement
A worn, damaged or incorrectly installed timing belt can result in serious engine problems.
When replacing the belt, the condition of the associated components should also be inspected.
Installation should be carried out according to the correct Yamaha workshop procedure, including correct:
- Timing mark alignment
- Belt positioning
- Tensioning procedure
- Inspection of associated components
If you are not experienced with engine timing, we recommend installation by a qualified marine technician.
Important – Please Check Compatibility
DO NOT ORDER BY HORSEPOWER ALONE.
Yamaha uses different timing belts on different engine generations with the same horsepower.
For example, other Yamaha 25–60 HP 4-stroke families use different timing belt part numbers.
Before ordering, please check:
- Engine model
- Engine serial number
- Engine year
- Existing timing belt
- Yamaha OEM part number
Your engine must use:
6C5-46241-00
If the timing belt looks the same as yours, this does not always mean it is the correct one for your outboard.
If you are unsure, please send SSI Marine your complete engine model and serial number and we will be happy to help confirm the correct belt.
