random misfire

[Cut n' Jump]

I figured out an intermittent misfire on my 70hp omc last year. Just thought I'd share my find.<br /><br />The connections on the powerpack to the sensor coils were oxidized. Not really visible corrosion, but just a darkened appearance. First time I 'fixed' it I just wiggled the wire then tightened up the connection. Misfire came back on next outing.... Then I recrimped the terminal and scratched the connection real good.<br /><br />Runs perfect always after that
