My ignition key and wire harness is all messed up. How can I jump start engine/outboard?<br />it is an Evinrude big twin, year I do not know, model#40353D serial#E01421.<br />The boat is a 14ft starcraft, the control and cables do not seem to be for this boat, cables are way too long (13ft) what size cable do I need? or how do I measure this?
