92' Yamaha 115, 2 cylinders on left side not getting spark

[Northcal01]

So I just bought a 92? Pro gator and it has a Yamaha 115 and the two cylinders on the left side of the engine are not getting spark. I checked the compression and they are 124 psi and 125. I pulled the flywheel off and checked to see if there was any rust and it looks really clean. I?m do not have a lot of experience in boat motors and I?m looking for some way of trouble shooting the problem. Can anyone give me some ways to narrow sown the problem?
