I know that when new rings are installed in 4-cycle engines that it is
generally recommended that the cylinder walls be honed to remove the glaze,
so the the new rings will seat properly. Is the same true of 2-cycle
engines?

I expect it is, but I just thought I'd check.

Most cars are plain cast iron: most outboards are plain aluminum.

Most aluminum cylinders have a sleeve of another, harder material. A
"plain aluminum" cylinder wouldn't live very long.

I think the only "aluminum" cylinder was the Chevy Vega.

I think you are wrong about that, as well.

The cylinder bore was silicon in early models and they later switched
to iron sleeves. They had additional woes due to the iron head mated
to the aluminum block.

I think you are correct.

Aluminum can be hard anodized however, resulting in a surface hardness on
the Rockwell scale very close to steel.
