I bought a boat and the owner had lost the key. I have a few questions I hope someone can help me with. The motor and controls are a 1970 Mercury 1150 Inline 6 115 Hp. Does anyone know if I can bypass the wires to start it and which ones? He also gave me an ignition switch with a key, but it does not appear to be for a boat. The switch has 6 wires: Purple,black,red,black with yellow stripe,yellow with black stripe and yellow with red stripe. Is there any way to hook this switch up so it starts at the dash and how would I wire it?
