I have a 1985 90 hp 6 cyl mercury motor . Yesterday it did some wierd stuff. Sometimes it is a slow starter and after I crank it for a few seconds it makes a humming noise and wont try to start again till humming noise goes away.

Well last night I ran across the lake and when i stopped and turned motor off it was making this humming noise . We could not figure out how to stop it . So i take key out of the ignition and it is still humming. We had to take battery cables off to kill the humming.

This has to be the ignition sticking open and not the starter right?? If it was just the starter it would quit when I pulled the key out I think.

Any help here greatly appreciated.
