My dad has a 1973 (74?) OMC inboard 250 hp 5.7 liter engine in his boat. We lost the owners manual somehow about 5 years ago. Does anyone know what the timing should be? Thanks.
I apologize if this is an ignorant question. It might be written on the motor but the motor is at my dad's house and I am trying to prepare to tune it.
