I have a 1997 and 2001 jet ski that I just bought. Both started up when I bought them. After sitting a day or so both batteries are dead. Neither will even turn over. After I charge them they will start up. After I charged the 1997 I took it to the lake
it started right up but then died a few seconds after being in the water. If anyone can help me with either of these problems it would be much appreciated.
