3.7l to many volts to coil???

Re: 3.7l to many volts to coil???

So the repair guys told me the engine is overheating, I just replaced the impeller and when it has the issue it doesnt show signs of overheating. He seems to think something may be lodged in the cooling passages, does this sound right???

I do like my petronix. I just wrote this in another thread the other day, so I just copied it in:

FYI I have the same engine. Mine is a Petronix Ignitor II (91146A $115) with a Flamethrower II coil (45111 epoxy $47) the oil filled would also work (45011). Would recommend getting both the Ignitor II and coil. If you go with the Petronix and flamethrower you will need a full 12V to make it work properly, so on instillation remove the purple resistance (you don't have to cut it off, just tape it off out of the way) wire from the coil + and splice a stranded wire into the purple wire going to the choke (I used solder and a couple of coats of liquid tape), run that wire to the coil +, that will give a full 12V for the Petronix red wire.

I did exactly the same thing on my boat about 5 years ago.

When you removed the old impeller, was it missing any pieces? They can sometimes find their way to the front of the heat exchanger.
