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

As often happens with old Mercs, the recoil likely let go at some point. Rather than repair the existing recoil, someone may have swapped on another recoil, in this case one from a 1955 Mark 55. It’s also possible he entire upper end has been replaced, as the gap at the carry rail in the rear is not present, also noted above. The lower unit, as has been noted above, is Mark 50, as evidenced by the lack of Dynafloats, and the presence of the copper tube exhaust relief. Another telltale will be the cylinder block, as Mark 50s have a sand cast block. But, first gen Mark 55s also had sandcast blocks, too, so it’s not a slam dunk. A mix of parts, for sure…
