1998 90hp evinrude engine won't shut down.

[mav6759]

I have a 1998 Evinrude 90hp. The problem I am having is the engine keeps running when I turn the ignition off. I have to choke the engine by pushing in the key to shut it down. Any ideas...

Thanks Mav.

(Ignition Kill Circuit)
(J. Reeves)

A Black wire (ground) should lead from the powerhead to the powerpack. There will also be a Black/Yellow wire leading from the powerpack to a raised "M" terminal of the ignition switch. To complete the circuit, there will be a Black wire from the other "M" terminal of the ignition switch to ground.

When the key is in the OFF position = The two "M" terminals are connected,. effectively shorting/killing the ignition.

When the key in ON position = The two "M" terminals are not connected and the ignition is engaged.

Get out your ohm meter and check the continuity of those wires and the ignition switch.
