Transom Bracket DF150-1234567-23 DF150: Model designation; 1234567: Production code; 23: Year code (potentially indicating the year 2023 or a similar internal code). The last two digits (or a portion thereof) often represent the year of manufacture, although the exact interpretation can vary and requires consultation of official Suzuki documentation or a dealer.
Lower Unit (Less Common) DF150-8901234-18 DF150: Model designation; 8901234: Production code; 18: Year code (potentially indicating the year 2018 or a similar internal code). Similar to the above, the last digits or a specific sequence within the code might indicate the year. Consult Suzuki resources for precise decoding.

Note: The specific meaning of each part of the serial number may change slightly depending on the exact year of manufacture. The examples provided are illustrative and should not be considered exhaustive. For definitive year identification, it is best to consult an authorized Suzuki dealer or reference official Suzuki documentation.

Decoding the Suzuki DF150 Serial Number


Determining the manufacturing year of your Suzuki DF150 outboard motor is crucial for maintenance scheduling, parts sourcing, and understanding its overall history. While Suzuki doesn’t publicly release a comprehensive decoder, the serial number itself holds the key. By understanding its structure and applying some detective work, you can pinpoint the approximate year of manufacture.

The Suzuki DF150 serial number, typically found on a plate affixed to the engine, is a combination of alphanumeric characters. Unfortunately, there isn’t a universally available online tool that directly translates these numbers into a year. However, the serial number’s structure provides clues. The first few characters often indicate the model and manufacturing location, while subsequent digits or letters represent the sequential production number and, indirectly, the year. This method requires careful examination and comparison with other known serial numbers or dealer records.

Serial Number Structure and Interpretation

The serial number is not a simple year code. Instead, it’s a sequence reflecting the manufacturing order. Therefore, identifying the year requires examining patterns within the serial number structure and comparing it to known production data. For example, a serial number starting with “05” might indicate a model produced in 2005, but this is not always a guaranteed rule and needs verification. The serial number’s middle section often incorporates a sequential production number which can help in approximate dating. Later characters might reflect internal production codes or checks. Unfortunately, without access to Suzuki’s internal manufacturing records, precise year determination solely from the serial number can be challenging. However, comparing serial numbers from known-year engines (perhaps obtained through dealer records or online forums) could provide valuable context and help establish patterns.

Utilizing Dealer Records and Online Forums

Accessing dealer records or participating in online forums dedicated to Suzuki outboard motors can significantly aid in decoding your DF150’s serial number. Dealer records, if accessible, might directly link a specific serial number to its manufacturing date. Online forums often have experienced users who have accumulated knowledge about serial number patterns and manufacturing years. Posting your serial number and model information on these forums might yield valuable insights from fellow Suzuki DF150 owners who have already successfully determined their engine’s age. Remember to be cautious and verify information from multiple sources.
