I have a 1974 Cota 247 with matching engine and frame numbers 21M16172. I removed the tool holder today and noticed that 17 is stamped on both the left and right crankcases just in front of the rear engine mount, and I have no idea what this means???? The full engine number is stamped in the usual place just behind the front engine mount. I have checked the parts manual but no clues there

I don't suppose it really matters that much but I am just a little curious. Can anyone shed any light on what it might signify?

Thanks

I suspect that would be the pairing number for the matching halves of the crankcase when it was ground.

Hi Hagsta im guessin this could be so as both my 348 motors have this as well as the motor nos they are 17,28 stamped on both halves at the rear mount top,,,,,,

PA is right! matching cases!
