Do you think if I painted the [outboard] rudders on my sister's scow
yellow it would become seaworthy?


"Seaworthy" always must be evaluated in terms of intended route and service.
Based on prior service record of yellow outboard rudders in this newsgroup,
your sister's boat after such modification should be prefectly adequate for
sitting on a mooring for years without going anywhere while she pesters and
blusters about being the worlds greatest sailor.
