Hi, I bought a 2007 170CC end of Sept.
I used it a few times and parked it in my yard when not in use.
During rain, the nav lights would turn on even though the switch was set to off. (middle position)
I haven't used the boat in 3 weeks. I'm in S NH, so the cold weather is here and it has frost a few times. I went to winterize my boat the other day and I had enough battery to trim the motor, but not enough to start it. Wouldn't even turn it over.

Any reason the battery would be dead already?
My truck can sit way longer than this and still start.
My atvs have batteries, they sit all winter and then start right up in the spring.

Any advice? Or is this normal?
Thanks.
