first off, let me say hi, im completely new to jet skis, but not mechanics.

I recently inherited a 1990 Waverunner, 650. That hasnt ran in about three years, i put new gas in it, plugs, and a new battery. That at least got it to turn over, took the wires off and tested them with a screwdriver and there wasnt any spark, put a plug in the wire, same thing. Went out and got a new coil, wires and boots. Still no spark, the fuse is good. Im completely at a loss here.

Any help would be greatly appreciated.

I've got an 89' Waverunner with the same issue. I accidently connected the battery backwords and blew the fuze (rookie mistake I know). I replaced the fuse but no spark now. I bought a 90' waverunner off someone and am thinking of using the electric box from the 90' in the 89', but not sure they are compatible. When I tear mine appart I'll see what I can figure out about it and maybe will have something for you to try.

spark

sounds like you traced everything back for spark Except the CDI assembly, change that lets see...

You should check that the engine stop switch is not malfunctioning by bypassing it.
