Timing Belt / Cambelt for Yamaha 9.9 HP 15 HP 20 HP 4-Stroke Outboards

Premium-quality aftermarket engine timing belt / cambelt for selected Yamaha 9.9 HP, 15 HP and 20 HP 4-stroke outboard engines.

The timing belt is a critical engine component that keeps the crankshaft and camshaft correctly synchronised, allowing the valves and pistons to operate at the correct timing.

Yamaha's maintenance information identifies 6AH-46241-00-00 as the timing belt for the F9.9H, F15C and F20B engine families.

Timing Belt Maintenance

The timing belt is an important service component on a Yamaha 4-stroke outboard.

Yamaha's maintenance guidance recommends timing belt replacement every 5 years or 1,000 operating hours, whichever comes first.

Always follow the maintenance schedule applicable to your exact engine.

Important – Please Check Compatibility

Please do not order by horsepower or appearance alone.

Different Yamaha 9.9 HP, 15 HP and 20 HP engines can use different timing belts.

For example, earlier F15A applications use a different timing belt, so identifying the exact engine model is important. Yamaha lists F9.9C / FT9.9D / F15A against 66M-46241-00-00 rather than this 6AH belt.

Before purchasing, please check:

Engine horsepower
Engine is 4 Stroke
Exact engine model
Engine serial number
Existing timing belt
Original Yamaha part number

For the safest identification, check that your engine requires:

6AH-46241-00 / 6AH-46241-00-00

If the part looks the same as yours, this does not always mean it is the correct one for your outboard.

If you are unsure, please send us your engine model and serial number before purchasing and our technical team will be happy to check compatibility.
