Please help - don't know much about outboards but here's my problem. I have a mercury 60 outboard approx 1991 ( serial odo74257 ) that won't start. Turns over no problem but will not fire up. Removed middle spark plug ( 3 cylinder ) earlier to check for spark. Held spark plug with pliers and gloves on and had friend to turn over. Moved plug closer to block and had electric shock which caused me to drop pliers so didn't notice any spark, however the engine started straight away and was running. Turned engine off and replaced plug but still won't fire up. Have removed all plugs and cleaned, dried and replaced. Any ideas would be greatly appreciated.
Thanks
Thanks
