The serial number on a Mercury 90 HP 2-stroke outboard motor is typically located on a plate attached to the transom bracket of the engine.
This plate is usually found on the right side (starboard side) of the engine when facing the propeller, near where the motor attaches to the boat. The serial number is critical for identifying the specific model, ordering parts, and verifying the engine's history.
The serial number plate contains information, including the serial number itself, the engine's horsepower, and often the model year. If the plate is damaged or missing, you might also find the serial number stamped directly on the engine block, though this location can vary depending on the model and year of the engine.
