I bought a vintage 1975 version, and from looking at the stern it's obvious that there must have been a piece that fit in there to close the transom:
And yes, I know she's dirty. I'll clean her up, don't worry.
The question is, does anyone have any idea what went into that open transom? The PO had no idea.
I can cut a piece of something to fit, but I'd love to know what the original idea was.
You can't tell from the photo, but the bottom of the opening is about 8" above the cockpit floor. There are two drains going out the transom as well.
Thanks!
