Towing Plug

[oestlarsen]

So far tub revealed few real surprised. Frame seems solid other than the bulkead outriggers I need to replace and I can live with the minimal rot in the gas outrigger (structurally solid).

I am stripping all the old glue that held insulation material on the seatbox etc. A pain..

Ok - does anybody know:
1. Is this plug Original? Hole seems pretty "OEM" like.
2. Any known replacements to fit here?

Thanks!
Carl
