Bought by mistake but….

Not a tight fit
I gave them 3 stars I don't like doing that but these gaskets call for it they have to much play when it's on the screw, they should work out fine but I have 2 OEM gaskets that fit perfectly , I'm thinking if you tighten the screw to much it might spread ot the gasket and water could come in to the lower unit. I hope they work cause I just ordered and received a 24 pack. . O E M are more money but I would feel more comfortable using the original gaskets. It's such a easy fix why didn't they just make the hole a little smaller.

Does not fit a Mercury outboard
I don’t know what these are made for, but trust me, they will not fit the drain or fill plugs on a 2020 Mercury 115 Pro XS
