Which wires do you connect on the ignition to start the motor?

Re: 1972 Evinrude 100hp Ignition

To start:<br />Disconnect yellow and black wire from CDI unit. This wire will have to be grounded to kill the engine.<br /><br />Jumper 12vdc from HOT battery to red and yellow wire on the small post on the starter solenoid. This by-passes neutral and ignition switchs, If everything else is good to go, this will start the engine.<br /><br />c/6<br /><br />Hooty

Hooty is correct.... <br /><br />Thats a hydro electric...<br /><br />even when the engine is working fine and the grear case is in neutral.. it will start in gear..<br /><br />Once the oil pressure in the gear case gets high enough,, it will switch to neutral.. but until that point, it will be in gear...<br /><br />rgds<br /><br />Franki

We can't find the yellow and black wire. What is the CDI unit? Does anybody have a diagram of the wires and their colors? They're a little old and faded.
