is a outboard prop and a inboard/outboard prop the same ? i got a 120 alpha 1 mercurzer out drive now would a prop off of a mercury 80hp out board fit ? and are the lower units the same?
We need to know the year of each.
But near as I can tell the sku numbers don't match.
Very likely you will have exhaust leaking where the hub joins the gearcase.
