battery charging system

anybody had any experience mounting a battery charging system in a jon boat, I would like to mount one in a 1548 war eagle for the cranking battery and the trolling motor battery, I just wonder if the system will be OK being exposed all the time??
any thoughts would be appreciated

the Guest units are gauranteed to be waterproof.

I have used a Guest unit for 3 years with no problems. The boat stays in the driveway plugged in when not in use. </font id=“blue”>

thanks for the tip, Guest it is!!
