zxi wont start
 

I HAVE A 96 ZXI900 , MY SON FLIPPED IT AT THE LAKE YESTERDAY , FILLED THE HULL W/ WATER, WE BROUGHT IT HOME , WONT START ONLY CLICKS . I PULLED THE CYLIDER HEAD OFF , WHEN I TRY AND START IT THE PISTONS MOVE SLIGHTLY SO I DONT THINK ITS FROZE UP, I PUT A BATTERY CHARGER ON IT BUT THE BATTERY NEVER FULLY CHARGES, TRYED TO JUMP IT WITH A CAR BUT NO LUCK. COULD IT BE THE STARTER, BATTERY OR POSSIBLY FROZEN CRANK? THEIR WAS WATER IN THE HULL FOR OABOUT 30 MINS TILL WE COULD GET IT DRAINED. I HAVE READ OTHER POSTS ABOUT HYDRO LOCK? BUT I WOULDNT THINK THE PISTONS WOULD BUDGE IF THAT WERE THE CASE. THANKS IN ADVANCE FOR ANY GUIDANCE YOU CAN GIVE.
