My 1997 polaris jet ski keeps taking in water? what could this be??

Unplugged water tube, cracked water tube, bad drive shaft hull seal, hole/crack in the hull, cracked water box, broken exhaust jacket water seal, water tubes plugged in incorrectly, no cap on flush kit, broken fitting on motor,etc. Dry out the boat take off the seat and place it in the water and look to see where the water is coming into the hull.
