Hi guys I lefe my ignition switch on over night.The next time i used the boat the eng would start fine, run a little rough. and would realy start miss fire at about 2500rpms thew out the day. after short slow runs it seemed to be getting better about 3500rpms and slowly it started to get worse again.what would likley be the problem a coil or ignition mod. it kin of feels like everything is breaking up. so I am leaning twards a ign. mod. any input would be helpfull thanx in advance
