Re: Newbie Please Help
I think what you are referring to is an "on-board charger." It is a device that hooks into the battery or batteries (if device is capable) and allows the user to simply plug into a wall outlet to charge the battery or batteries. Age of a boat is not a sure-fire way to predict whether one is present or not. They are most common in bass boats, salty boats, and other boats that have multiple battery banks because it greatly simplifies the charging process.
It is possible that your boat did not come with that option. If it's there it should be near the batteries. If not there, no big deal...you can add one ($100-$200) or just pull the batteries and place a stand-alone charger on them.
Or do what I do and disconnect it from boat, leave it in place, and attach a trickle charger to it when not in use (w/ bilge open to ventilate, of course).
Hope this helps and good luck.
