Hi all.
I have an old Mercury 7.5HP outboard (1981 Belgium build). 1 of my ignition coils have cracked and the motor is now running on 1 cylinder. Looking around for a replacement coil I've come across this 3rd party cheap coil here: https://www.amazon.co.uk/TOOGOO-Out...=1&keywords=339-7370A13&qid=1592131929&sr=8-1
Here are pictures of my original coils (part no.: 339-5288T2)
As you can see, there are a couple of visual differences. The 3rd party one from Amazon has a small plate going from ground terminal to ferrite assembly and having searched for other images of this coil, I can see there is no grounding wire to contact with motor chassis like you see on my old once...
Can I use these new 3rd party coils on my motor?
How do I install the new coils correctly (wiring)?
Could these potentially damage my CDI box or other parts, if the voltages aren't exactly the same?
Any advice and guidance would be much appreciated here!
