1992 seadoo

Hey guys, My seadoo is sparking intermittently. The plugs are new and when it does decide to spark, it's a nice powerful bright spark. I've checked the water proof wiring harness box to see if anything is loose or damaged and everything looks brand new in there. The first time I got it to...
