83 evinrude 90hp need replacement coils..

[Jstorres486]

Hi guys I got an 83 evinrude 90hp with power trim and tilt.. I’m trying to replace coils but what I have is a little weird and can’t seem to match new ones to it.. I have 2 identical coils and 2 different ones.. I took some pictures.. my question can someone point me in the right direction on which coil set to buy.. thank you. This is what I have now seems like there’s 2 different coils

Strange that you would need 4 coils.----But the only difference is the orange wire and how it is attached.----What is your motor doing not doing ?

Thanks for the reply. The motor is new to me just got from a friend.. he had it in storage for a little while.. yesterday I had it out and while I’m Wot I feel a little misfire and spluttering.. was thinking of changing all coils and spark plugs to start off

Do a compression test first before spending any beer tokens on coils.----Post the numbers here.

Did that Wednesday… 125 on all cylinders I don’t know if this makes a difference but we did it cold and also hot after running for 10 minutes or so and got same compression 125

Next is to run with a timing light ( one cylinder at a time ) and see if you can find a cylinder with a miss.
