Does anyone know if Honda lower unit Part No. 41100-ZW4-H13ZA ins interchangeable with Honda lower unit Part No. 41100-ZW4-H16ZA.

I have a Honda BF-45 motor (41100-ZW4-H13Z) and I was wondering if the 41100-ZW4-H16ZA would work.

Thanks

I didn't look to see what the part numbers were, but I can tell you that all the lowers are interchangeable from about 2005 or 6 on back (35-50 hp carbed motors). The only external difference I know between them is the seal on the shift shaft. They changed that around a little, but it make no difference on the "swapability" of them.

Just to confirm what ahicks said in the post above, according to Honda Power Equipment Customer Support, "The part number 41100-ZW4-H13ZA has been superseded to the 41100-ZW4-H16ZA that is currently available".

So the current replacement part for this Honda BF-45 motor is "41100-ZW4-H16ZA".
