Dan,
I live not far from you down in Rockport, TX. The Texas Maritime Museum here in Rockport used to have a collection of vintage outboard motors they kept on display, and would rotate the display every few months. I know the Museum suffered some damage during in Hurricane Harvey back in 2017 but they are back in full operation now (well, reduced hours due to Covid-19). Could be they might be looking for some new donations if they lost some of the motors to the storm, or might be looking to add to their collection.
