I just bought a boat with a 25hp evinrude (dont know exactly what year). I think it is a 1970's model. I dont know if it is 50:1 or what. any ideas ??

I had an older evinrude, older 70's 15 hp. I used 32:1 ratio. I know that in the 60's it was ridiculous 24:1 and has been raised with every year.
You should be safe at 32, if it smokes too much reduce slightly. Meanwhile, if you reply with model and serial number i can look into it for you.
