Just bought and installed electronic conversion kit and have a Q

[brando15]

Hey guys I have a 1987 mercruiser 120 hp 153ci. I just bought the kit to convert and installed everything and it works great. I immediately noticed starting was night and day. Now I just looked at the box and I was sent the 1.5ohm coil. I understand I am suppose to use the 3ohm coil so I called the parts store back and they told me the 1.5 would be more appropriate for my application since it will be used at high rpm(racing) my question is" will I run into any issues with this? Is it actually better to use with my application? Will it overheat and will I lose any performance over the 3 ohm coil?

Thanks in advance
Brandon

I just looked in the store and the store says I can use the module with coils 18-5466 & 18-5469 the first one says its for 8 cyl and the second is for 4 cyl???

I checked the ohms on my old coil by the positive lead and neg lead off my tester and I'm getting 2.1 ohms. Tested on the new one and I'm getting a resistance of 2.8? Can anybody please help?

When you measure the ohms, you have to have the wires off the coil at least on side before you take your measurement.

When you measure the ohms, you have to have the wires off the coil from at least one side before you take your measurement.
