* 41 E: This likely represents the model year and possibly a sub-model designation. "41" might indicate the year (though Johnson/Evinrude dating conventions can be complex and vary), and "E" might be a letter code specifying a specific configuration within that year's models.
* 350: This is probably a horsepower rating (3.5 hp). This is a common designation.
* SN 373229: This is clearly the serial number. This number is crucial for identifying the specific motor's manufacturing date and details.
* DT 10: This is unclear without more context. It could be a dealer code, internal factory code, or even a part of a previous repair/service record.
* Johnson Seahorse: This is simply the manufacturer and brand name.
