trying to get the correct coil
trying to get the correct coil for 1977 140 johnson as 1 has a crack. have gotten 2 replacments that differ in apperance and ohms. the engine has 3 hole green coils with integrated plug wire and the replacments are both 2 hole black with seperate spark plug wire. new ones ohm at 285 old ones at 1350. it has 1 power pac assembly. are these interchangable with such a big differnce in ohms?
Thanks
Tony
