OEM and Cross Reference Numbers

Use the following part numbers when identifying a replacement timing belt for a compatible Yamaha outboard.

What This Timing Belt Is Used For

The timing belt is a critical component of the Yamaha four-stroke outboard engine's valve timing system. It connects the crankshaft and camshaft timing components so that the engine's valves open and close at the correct points in the combustion cycle.

Maintaining accurate valve timing is essential for proper engine operation. A worn, damaged, or incorrectly installed timing belt can affect engine performance and may lead to serious internal engine damage.

Primary Functions

• Maintains crankshaft-to-camshaft synchronization.
• Supports accurate intake and exhaust valve timing.
• Provides positive engagement with the timing pulleys.
• Supports proper operation of the engine's valve train.
• Serves as a replacement during timing system maintenance.

Important Fitment Note

Yamaha 6DA-W4624-00-00 does not fit every Yamaha 150-200 HP four-stroke outboard.

Yamaha has used different timing belt designs across F150, F175, F200, LF, and VF engine generations. Some engines with similar horsepower ratings require a different timing belt.

The supplied application records identify numerous model configurations under the catalog designation 2006 and Later. This designation should not be interpreted as confirmation that every listed engine family uses this belt in every production year from 2006 to the present.

Before ordering, verify your complete Yamaha model number, engine serial number, and original timing belt part number using the correct OEM parts diagram.

Compatible Yamaha Outboard Applications

The following application chart organizes the supplied Yamaha model listings into readable engine families. It includes standard F-series engines, LF counter-rotation models, and specified VF V MAX SHO applications.

Source catalog designation: 2006 and Later. Exact production-year applicability must be confirmed using the Yamaha parts catalog.
