ok first of i just recently purchased two seadoo pwc, a 2004 seadoo GTI LE and a 2002 seadoo GTX DI. i tried starting the 04 GTI LE and all it does is barely turn over like a dead battery. these skis have been sitting unused for quiet a while. previous owner says it runs. any way i put battery to charge i tried it again today and now it cranks like its stuck then jus stops and the starter sounds like it continues straining. then when i try again it jus beeps and a red light near the oil symbol illuminates and everytime i push the start button it jus beeps. so i pulled out the lanyard and put it back in and it allows to try to crank then beeps. what do you think this can be. now on the 02 he said he was using it and it jus shut down on him and didnt start back up so he jus left it sitting. he claims to say it ran low on oil what could this mean a new motor? or should i try starting this one as well. im thinking on buying new batteries but dont know the specs to order a marine battery from my employer. any and all help is greatly appreciated.
