quote Buccaneer:
The next video on Mercury’s 50,000 mile endurance run
was a blast from the past too.
Couldn’t help noticing the Waterman plug (Evinrude NOT first in outboards) at the top of the video, and later (around 19 minutes in) about the superiority of inline-4 and inline-6 engines, NOT "big twin", V, or inline-3.
Funny, how mercury eventually made a big twin (1963 350– same bore as the OMC 25hp big twin), an inline-3 (1976 650), and a V-6 (1976 1750).
