]Ok, I think I bought a massey 1450(that's what the hood says anyway) a few months ago. But I'm not sure the serial# is 24206121 and the model # is 1650A. How can I tell what engine I have I can't find any tags on it??? Are there any telltale signs from a 14 h and 16h???? I could really use some help I have a leak where the drive shaft enters the hydro/tranny? and I the skill to do the work but don't know the part number, because I don't even what I have??
