I've seen a few projects with this done already but I'm thinking of cutting a hatch in the front seat of my sears 1436 and mounting a swivel seat on a hinged door with turn-loc fasteners to secure it while underway.I also have an on board charger that will be hidden in the compartment as well .I'm thinking of going total electric on this boat just curious if I need 2 batteries or one large one to run a Minn Kota PD 45LBS trolling motor, Navigation Lights,fish finder, and possibly an inverter or LED lights for night fishing. Any ideas or links to similar projects will be appreciated .
