Had spark for a while this summer now it is gone. Would like to check the kill switch & ignition key switch. What color is the wire for the kill switch?

Thanks in advance Keith

Disconnected that wire still no spark. What is the proper way to test the ignition switch?

The switch is disconnected when the wire is unplug here is a test for the ign. system.

Performed The Tests With A Ohm Meter, Everything Seems To Be In Range. Still No Spark. I'm Really At A Loss Now! Anymore Ideas?

Is there a mercury tilt switch on this Mariner?

Re: 50hp 1983 mariner lost spark

Yes, but with the black/yellow disconnected that eliminates the switches and wiring. If all the windings are within specs. the switch box almost has to be the culprit. A ohms test is not a good a a DVM/DVA test but should be alright to test for your problem.

Ok! I replaced the switch box, a little pricey, I also changed the rectifier it wasn't up to the test specs in the Clymer manual. What a nice big blue spark now!! Thanks for all your help!!!
