Hey guys i know im new to the forums but i hope u can still help me out. so my uncle took a girl to the river with my seadoo who wasnt so smart and she sucked up a rock and it jammed in the impeller. she kept trying to start it over and over with the rock jammed. it kept trying to turn over but couldnt and then just stopped all together. my uncle unjammed the rock then tried charging the batter and tried to start it up. it didnt make a sound. he then took the plugs out and tried to turn it over and it kinda lightly attempted. i have no idea whats wrong or where to start looking. anyone have any idea what it could be? i appreciate any advise for help. thanks.
