Other Help with engin size

[Spudhunter]

I have a 1981 honda 4 stroke and I'm trying to figure out the engine size. Can anyone help with this?

Size of engine is stamped , cast into jug . Should have marking in cc 124 , 249 ,, 305 , 348 , this is cc . Round off to nominal size , 125 , 250 ,,, ect.

This is the only stamp I seen on the engine. But it has cm and not cc

500cc would be the designation most likely. 'CM3' and 'cc' both mean a cubic centimeter.
