1995 75 hp 3 cyl mercury no fire

[marti110]

After ebing stored inside for the winter my 75 hp mercury 3 cylinder will not start. the last time I was out it ran perfect. It doesn't seem to be firing and to be honest I don't know much about it.How do I go about tracking down the problem?

Check your kill switch. If it hasn't been engaged check for a strong spark at all plugs.

I don't think it has a kill switch. No spark at any of the plugs.

Theses engine have a kill swith and engaging it will cause exactly this condition.

Where would the kill switch be located? I don't see anything on the dash.

it is under the key switch on the throttle.

Turns out it "did" have a kill switch but it has been bypassed by the former owner. Got to looking at all of the wiring under the dash after I noticed this and found a fuseable link for the kill switch that is blown. I had to go to work and didn't have time to try and start it but I am going to replace the fuse and see if that will do it.

I'm having the same problem - no fire at the plugs, starter turning fine. Will replace kill switch tomorrow, but wondering what next steps will be necessary if that isn't the problem. This on a '95 Mercury 75 HP outboard on a Fisher Freedom 240 Pontoon Boat.
