Hercules Engine Serial Number Registry

This serial number registry has been compiled through the years primarily by Glenn Karch. If you have a Hercules built engine that is not in this registry, please fill out and submit the Registry Form and it will be included. Also, if your engine is in this registry and you have purchased it after 2010, please fill out and submit the Registry Form so the registry can be updated with your current information.

If you have multiple engines to register, you can download the blank Excel file below, fill out the information for each engine and then email the Excel file to mike@tuckerhill.us.
