Great Crush Washer
It's a crush washer that fits and is much cheaper than the OEM alternative. What more is there to say?

Looks workabel
I have 1996 115HP Yamaha 2 stroke. 12 the gaskets look be correct size the other 12 are larger and may fit a 4 stroke motor no way correct size for my lower unit. But was good price and 12 gaskets will last a few summers, as I use my boat commercially crab Potting.
