How many ohms internal resistance does the coil have?
The technicians at Sierra have said that it is an external resistance coil, and that it has no internal ohm resistance. If you have any further questions contact us at the number at the top of the page.
My 1985 3.0 mercruiser does not have an external resistor, is this the right coil?
The technicians at Sierra have affirmed that all of the 3.0 Mercruiser engines from that year should have an external resistor. If yours does not, then you will want to consult a Mercury dealer for guidance on what to get. Because all of the information we have on this motor points to this ignition coil working for it.
