Default oil to gas ratio

Hi, I just bought a used boat w/ an 1989 80 hp mercury ob. I am told
that the motor did have a oil resivior but was disabled to allow a
premix. Can anyone tell me the proper ratio to mix. I think it should
be 50:1 but am unsure thanks.

50:1 but you may want to consider 40:1 due to the age.


OK thanks for the quick response!!!!
