i have a 1992 johnson 200hp GT sometimes you turn the key and motor cranks but has no spark at all plugs so i remove cover and unbolt the power pack and reattach all ground wires and it fires right up bolt it back together and it runs great never missing a beat i can stop and start all day long and never have a problem.take the boat home and a few days later the same problem ive taken it to a few boat shops and of course it runs fine when there. but a few days later it happens again the motor runs great when running im thinking there has got to be a bad conductor at a connection somewhere any ideas would be greatly appeiciated<br /><br />thanks Bill
