I purchased a used excall last August and I love it.But I thought I read something last summer on the forum about apllying silicon somewhere to prevent water leaks. I do notice that when I unscrew my battery pack that there is some type of gaskat or something that appears to be loose. Any help with this or any other tips would be appreiciated. I'm planning on getting in the lake this Sunday and Monday and I don't want to do anything to harm the machine. HH@ THANKS TO ALL!
