Important – Please Check Compatibility
Please do not order by horsepower alone.
Yamaha produced different engine families within the 20 HP, 25 HP, 30 HP and 40 HP ranges, and not every Yamaha engine within these horsepower ratings uses this timing belt.
Before purchasing, please check:
- Engine horsepower
- Engine is 4 Stroke
- Exact engine model
- Production year
- Engine serial number
- Existing timing belt
- Original Yamaha part number
For the safest identification, check that your engine requires:
65W-46241-00 / 65W-46241-00-00
If the 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 engine model and serial number before purchasing and our technical team will be happy to check compatibility.
