Fuel/oil ratio for 1966 Chrysler 50HP

[built4speed]

Hi all, first post. I just picked up an old 60's fiberglass 14' with a 1966 Chrysler 50 horse motor. The guy I bought it from couldn't quite remember what fuel/oil ratio it used, but was pretty sure it was 50:1. Does that seem right? Not sure if this is old enough to need 24:1 instead. Any advice is greatly appreciated. Thanks.

I do not have that type of motor, but generally, 50:1 is the correct ratio.
