Does anyone know the real difference between part number 813563T1 and 813563A 1? They are listed as alternate parts but have a price difference of$200.
What does the "T" and "A" represent?
Can I pull the powerhead off a 1998 150hp (DFI) Bluewater Mercury long shaft and replace it with a powerhead from a 1997 175hp (EFI) short shaft? I don't think the shaft lengths matter but figured I would mention it.
Thanks
John
