My local Mercruiser mechanic suggested I replace my Blue Streak coil as it was not suited for my engine.
Problem is that we have tried two different coils (PerTronix 40,000v and another brand I can't remember) and they both produce the same result, only starts at high rpm and stalls below 1700 rpm.
1977 Mercruiser MIE 330
S/N 5551947
IGNITOR EIectronic Ignition ML-181
Blue Streak coil (MUST USE AN EXTERNAL RESISTOR)
What does an external resistor look like?
Not sure what to do next.
