Model # WBA6506A56
Serial # C1808

Can anyone help me with the year of manufacture, horsepower and any other information you can provide.

Probably a 1960's made by West Bend or Chrysler...
same difference Chrysler bought West Bend 1964-65.
Chrysler sold to Force and Mercury bought Force
to run as Mercury Marine....believe it or not
a Mercury dealer may have or be able to supply
some parts.
Mercury, Oliver, Scott/Maculloch and Eska also
supplied outboards to Western Auto under
Wizard brand...
