I have a mid 70's Mercury 850 with Thunderbolt ignition. It runs well but only when the battery is connected. Any ideas? T :cool: hanks

Re: Need advice

Why would you disconnect the battery while it is running? I am not sure about this motor but on some you can damage some very expensive parts doing so.
