I've recently bought a boat with a 1959 35hp johnson/evinrude(?) seahorse motor on it. this is my first boat and even though i'm an engine mechanic by trade, i have no idea how to work on a boat motor. while inspecting the motor i discovered that the main wire harness that connects to the motor has some corroded and broken wires in it. is there any place that i can order a new wire harness and possibly a service and repair manual for this motor. any help would be much appreciated. thank you
