I have no idea. I think it was manufactured in 1969.
If I see him tomorrow I will let you know.
The roof looks like it was poorly resurfaced fiberglass. Although painted, you can still see the imprints from a course fiberglass mat. I am assuming it is not the original.
I believe it is an inboard/outboard single engine. I never looked at the stern. with what I think he said was a 30 gal gas tank. I thought that was awfully small, so that too may have been replaced.
I will probably see him tomorrow.
