Ive just purchased my first boat complete with 1979 140hp Evinrude engine. good news however im stuck regarding the fuel to oil ratio.
Do anybody know what the fuel to oil ratio is? The previous owner stated that is 20:1 but on a website i found a ration of 50:1, does anyone know or where i will be able to find out??
Im new to this and not very technical so what will happen the ration is incorrect?
Any help / advice would be very useful.
