1978 175 Evinrude Jet & want to get some input on what oil / fuel mix ratio to use. I was told to use 75 to 1 Oil Type (Amsoil HP injector) I was running 65 to 1 on my 1976 115 Johnson without any problems (same oil)
Both boats used mostly around 4000 to 6000 elevation in SE Idaho
Thanks for any recommendations
