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.

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

Works like it should
These work as well as the original Yamaha gaskets I've used. One purchase should last a few lifetimes.
