Nylon.------Gears are expensive and the nylon factory washer lasts a long time if tightened properly.

Mercury has packs of 10 or so washers. For not much more than the price of just one
Some are Nylon, others can be other Materials

You are supposed to replace them every time you change lower unit oil

Just for grins and giggles I just looked up the Owner's Manuals for a few engines from the 1960's thru 2018. Not a single one says replacing the washer annually is a requirement. Maybe a good idea, but not a specification.

In my case I routinely run a 1955 Mercury and a 1964 Evinrude, both bought new, and both have the original washers. Neither one leaks a drop nor has any water intrusion.

In any event I do inventory washers and have replaced them if cracked or don't look too good.

Be aware that the current one may be jammed way up at the base of the drain hole. If so, carefully pry it out and replace it.

Water-cooled Gears and Bearings are not an Advantage, and if not caught early, can get very pricy. Reusing the old Washers has all the signs of being Penny-wise, Dollar-foolish

I always inspect the washer, screw and the seat, if anything has any sign of damage, repair and a new washer/gasket is used. I do not moor my boat so I can do visual checks frequently for any sign of leaking, so I rarely change the washer unless there is an issue. With that said...if I were docking my boat and not able to do regular checks, then replacing the washer each time would be a wise move!!! Can honestly say in my 60 plus years of boating, never had a LU leak.
