What This Timing Belt Is Used For

The EMP 6DA-W4624P timing belt is used during maintenance or repair of the valve timing system on compatible Yamaha four-stroke outboards.

The timing belt transfers crankshaft rotation to the camshaft timing components. This keeps valve movement synchronized with piston position throughout the engine's operating cycle.

Timing belt condition is important because damage, excessive wear, or incorrect installation can affect valve timing and potentially cause serious engine damage.

Common Service Applications

• Scheduled engine timing belt replacement
• Timing system maintenance during powerhead service
• Replacement of a worn or damaged timing belt
• Service following timing belt contamination
• Timing belt replacement during related engine repairs

Important Fitment Note

EMP 6DA-W4624P does not fit every Yamaha 150–200 HP four-stroke outboard.

Yamaha uses different timing belt configurations across engine generations. Similar horsepower ratings and model-family names do not guarantee that the same timing belt is required.

The supplied Yamaha application data identifies the engine models below under a broad 2006 and Later catalog category. That category should not be interpreted as a verified continuous year range for each individual engine.

Confirm the complete Yamaha engine model, serial number, and original OEM timing belt number before purchasing.
