Good Luck

Tech Info is worth a look if you have a MERCURY,WIZARD or Sea King
single made by Kiekhaefer Corporation from 1940 to late
1950s. Year, Model, Bore, Stroke, Displacement, point and plug gap,
fuel mix (pre TCW-3) weight, prop
pitch and diameter Horsepower and rated RPM… in short ANSWERS to
ALL the USUAL Questions.
In reference to current question
Tech Info shows displacement ANd
the Bore and Stroke so variations
between models can be understood
better.
I believe this information is also posted on AOMCI site.
