problem with mercury 4 stoke 2003 90 hp

[basilis]

hello! i have mercury 90hp 4 stoke 2003. i have a problem with my outboart engine. it has only 100hours of working. it has two ignition coils and the ignition coil that gives voltage to number two and number three cylinder does not work. i try to change the place of the two ignition coils and after the change, the cylinder 2-3 didnt work and the 1-4 cylinder worked. so i realized tha the problem was that the system that gives voltage to one of two ignision coil does not work. so what can i do? thank you very much!
