year of Johns 10HP and 9.5HP

[knorris47]

We have 2 Johnson motors that we have no idea the year.
1. Johnson Seahorse 10hp Model QD-21 serial #2039976
2. Johnson 9.5hp Model 9R-73B serial# J3766034
My husband has assigned me the task of finding the ages and manuals for them. Any help would be greatly appreciated!!!
Thanks
Karen

Thank you so much. That should make it easier to find an old manual.
