Reply To: 1954 Mercury Mark 50 who has one ,is this one

There are a lot of things unique to the MK 50 some of which were carried over to early MK 55s as Mercury never threw anything away just used the parts on the next model until gone. The carbs were different, the electric starter was different, the electrical connection was different, the lower unit had three or four small holes for the water inlet,( these were often drilled out to solve over heating issues). The prop shaft had a different number of splines. That is all I can think of off the top of my head. I have a MK 50E short shaft and did some extensive research which I posted about 2008-2009. I will look and see if I still have Info. I also have some info and pictures which I think came from the “old Merc” website. Not sure if that is still up or not.
