my boat won't trun off

I had the same problem with my MSD 6AL box. The problem on mine was the exciter wire going from my key to to alternator and the power wire from key to MSD box were on the same terminal on my key. Power from alt. was feeding MSD box and not allowing it to shut off when the key was turned off. I tried diodes with no luck I ended up having to separate the two wires. I had to get and new key that had 2 terminals for switched power. Hope this helps.

Without a doubt the ignition switch is bad! get a new switch and that will do it!

I've had the exact same thing happen before myself.
