Year, HP and fuel/oil mix

[Fisherman51]

Just purchased a used boat with an Evinrude StarFire IV outboard model no. 50529B, serial number 03114. Can anyone tell me the year, hp and fuel/oil mix on this outboard? Thanks!

Re: Year, HP and fuel/oil mix

1962 model 75hp.Fuel mix ratio largely depends on whether your engine has needle type or babbit type mains and rod bearings and in your case I am not sure.Babbit type(32:1) Needle type (some say 50:1)

Thanks, we thought it may be 75 hp but wasn't sure with the model number starting with a 50.
