25 HP Evinrude will not shut off

[ssface]

I have an E25ECIB, ser E001261, 1981 Evinrude that will not stop running when I turn the boat console ignition switch key off.
The problem started when I replaced the old corroded positive battery cable with a new one.
I replaced the ignition switch with a new one and still have the same problem???
any help would be appreciated,,,,thx

not sure how to diagnose this for you, but I will say to keep in mind that a boat motor is different than a car motor. When you turn off a car motor, it kills the connection to the battery and the motor dies. When you turn off a boat motor, it actually does the opposite and grounds out the motor so there is no more spark... I THINK that is what I learned.

Long story short though, you can start a boat motor, then disconnect the battery and it will keep running :-)

Still haven't figured this out...

If you have a manual, follow the wires from the ignition to the coils also see if you have any inline wires to the motor that may have come loose. Most boat motors work the same as your lawn mower, a ground is created that starves the points or what ever of juice which kills the motor.
