Jet ski wont get spark?

[aredxwrestler112]

I have a 91' Polaris jet ski. It has a 3 cylinder 650 in it. it ran before winter, and then afterwards it will not. I am getting compression and its rolling over alright, but it is not getting spark. Battery is fine, i tihnk it is the coil that is not working. What could be the cause, how to find out if it is or isnt, and how to fix the problem?
