I just picked up an early 70's Merc 800. It is extremely similar to my two merc 650s. It looks like the bore is the same, I am not sure about the stroke.
Does anybody know how they get the extra 15 HP out of the 800 vs the 650? What are the differences between the two?
Also, does anyone know if the lower units are interchangeable? same ratio?
