I have a 24p Trophy+ I bought and ran one time on my 1998 Mariner 175 EFI then threw on the shelf for a spare. My FIL has a 1989 Ranger with a 150 evinrude on it that needs a new prop. Their are no visible stamps on his prop so I have no base to go off of. Will it fit his evinrude and I am assuming I will need to change out the flow threw hub does anyone know the part number?
