Fuel/Oil mixture for 55 hp Chrysler

[swimmin' for shore]

I believe the motor is a 1972. The model number is 557HF. The serial number is 5252. Anyone know the gas mixture for this, or how to find out? Thanks in advance.

I used to have a 20 chysler and we mixed the oil at 50to1 never had any problems.

50:1 is the correct ratio for that motor.
