"Steven,

Is it a 6 cylinder engine?

Model 175:
  • 6 cylinder
  • 4 x 4 13/16
  • 363 cid
  • 175HP @ 3400RPM
  • Weight w/ direct drive 1050 lbs
  • w/ reduction drive 1250
I don't know the year. Maybe someone else knows. I would guess late 1950's to early 1960's, but that is just based on the model, not the serial number.

That model is covered in the Maintenance Handbook for 4 & 6 cylinder engines."
