I had heard that back in the mid to late 1940s one of the west coast racers/motor builders/parts suppliers cast a Evinrude Speeditwin driveshaft housing in bronze for "C" service racing.. It was also used for P500 pumper "F" racing conversions. I personally have never seen one.

This is the best lower unit. It was patterned off one dad modified.
