Johson Sea Horse 521cc

I have a Johnson Sea Horse 521 CC 20 HP model number J20CRCSA. Looking to find out how I can determine the model year and what the fuel mixture should be for this motor.

please check the number again, i can't match it CS would be 1948 but that doesn't compute.

I have checked it several times becasue I cannot find it anywhere. It is for sure J20CRCSA (well that is what is stamped on the plate). Shows to be made in Canada.
