4 years ago I had a 95 Tyee 1850, this boat had the movable floor piece up front with a pedestal mount. I just hid the two batteries under that, worked pretty well. I mounted the charger in the floor compartment in the bow.
My boat was a 4.3L V-6, 4 bbl with a Volvo Duo Prop drive. Not a whole lot bothered that boat as far as weight.
Think of it this way. There is seating for 2 - 4 people up front. Two batteries and a trolling motor doesn't quite weigh that much.
Now I have a Tyee 1950 Grand Sport with a 5.7L and Merc drive. 6 adults doesn't even phase it.
