Most common name is a body plug if its on a car ( they have heaps of them ) but I dunno what the outboard peeps would call it . You should be able to get one from an auto parts shop for a couple of bucks .:)

I'm not at all sure that this is the original plug. At least on my pre 1972 outboards there is a rectangular little metal plate, which is the same color as the rest of the lower unit, that is held in place by 2 screws. It is called a "cover plate"

Typical of a plug used on " offshore " small motors.----Honda refers to it as a grommet.

It looks like there are 2 motors. The blue one looks like a pre 1972 Evinrude, the other one I do not recognize.

These grommets are common on 70.es and 80.es japanese engines such as Suzuki, Yamaha, "japanese built" Mariner and maybe Tohatsu (Nissan).
Cover for the shift linkage coupler.

Or its a grommet that fits in an outboard driveshaft housing :).
To me a grommet has a hole in it .... like for getting a wiring harness thru a bulkhead .
Yep...have to agree with ya....I was always taught that a grommet fit inside a hole to protect the sharp edges from chewing up any wires or hoses that passed thru that hole in the grommet. If no hole then it was called a cover.
Years back made a tool ( mold) that cast these things from plastic and those were the names used by the mfgr. I guess there are some others that might call them doohickies, or whatchamacallits.
