I blew the alternator belt on my 2001 Seadoo Challenger on the weekend, it has a Merc 200hp M2 jet drive in it, I replaced the belt, now engine has a rough idle and hardly any throttle response. I was thinking of changing the spark plugs. The alternator belt also runs a compressor for the fuel (direct fuel injection). If anyone out there can help me out it would be greatly appreciated
