After resurrecting our old family motor and screaming along like she did back in the early '70s her prop spun. So hunting a replacement. My spun prop has this part # (48-334801 1,1 PROPELLER ASSEMBLY(2 BLADE - ALUMINUM - 11"PITCH). All props I've seen always start with 48- I've found the exact same part number for a prop that appears identical but it starts with 38- (38-33480-1) I'm pretty sure that the 2 digit number is the parts group. I can't find any reference to any 38- parts of any kind, except for Serial Number Tag. In the Ebay picture it is clearly a 38 not a 48. Will this prop work for me? thanks for any help.
