I thought I had my 1997 Seadoo GSI performance problems resolved. I found my charging voltage was too high and replaced the regulator/rectifier which cured that. However, it still has issues with loosing power upon acceleration and it's a definite missing out and not a surge. The new analog tach needle goes erratic when it happens and intermittently pops down to zero RPM but it never dies and if I shut it off it starts right back up and idles smoothly. Fuel filter, plugs, and plug wires are new, compression is good, had MPEC tested as good. Help fellas.
