Installation Notes
- Switch off the engine, allow it to cool, and follow the safety procedures in the applicable service manual.
- Remove the components necessary to access the timing-belt system.
- Before removing the old belt, align and record the timing marks according to the service manual.
- Remove the old belt and inspect the pulleys, tensioning components, and surrounding seals for wear or damage.
- Install the replacement belt without forcing, twisting, contaminating, or sharply bending it.
- Set belt tension and verify timing-mark alignment using the manufacturer’s specified procedure and torque values.
- Rotate the engine by hand as directed by the service manual and recheck the timing marks before final assembly.
- Because incorrect timing can cause engine damage, professional installation is recommended when the required service information or tools are not available.
Maintenance and FAQ
How do I confirm that this belt fits my outboard?
Confirm that the engine is a Yamaha F15 or F20 four-stroke model from 2006–2017 and compare the original belt or service-manual reference with 6AH-46241-00 or 18-15136. The model, horsepower, stroke, and year should all agree before ordering.
When should the timing belt be replaced?
The company maintenance note recommends replacement every 5 years or 100 hours of use. Actual service requirements can vary with operating conditions, so the engine manufacturer’s service manual should be followed where it specifies a different interval.
What are signs that a timing belt needs inspection?
Inspect the belt for cracking, fraying, glazing, damaged or missing teeth, contamination, unusual looseness, or other visible deterioration. If the engine develops timing-related running problems or will not start, stop operation and have the timing system inspected.
Is this an OEM Yamaha belt?
No. This listing is for an aftermarket replacement belt associated with Yamaha reference number 6AH-46241-00 and aftermarket reference 18-15136. Yamaha is referenced for application and part-number comparison only.
Does the package include a complete timing-belt kit?
No. This is a single timing belt. Additional timing-system parts are not included unless separately listed in your order.
