hello, i have a 2000 yamaha gp1200r millenium edition, its converted over to premix and has a d plate in it. when i start it out of and in the water the warning light comes on and starts beeping and i was wondering how i can make that stop? also when i slow down it sometimes stalls and when i try to keep it at 1 or 2 mph it stalls. also i shut it off and turned it back on about 20 minutes later and once i turned it on it jumped right to 10mph and was reving high but it was fine all day. when i got home i went to flush it and as i was had it running no water was coming out while i was flushing it. can some please help me and answer my questions to get my ski running and working properly? thank you all
