R. J. Smith's Six Cylinder
Mercury Outboard Conversion
This engine is in my collection and has the first of two rotary starter valve designs and ball bearing bash valves. After starting the bash valves took over and the rotary valve became a minor issue. Some of his early designs, as in the four cylinder Mercury I have, are only rotary valve actuated.
