I do not have this big a boat. Even with lithium battery’s. I think you would be draining the battery’s way to fast. Considering with that size boat you could be out in some rough weather. The electric would be nice for drift fishing. Are you getting duel big motors. If just a single big motor. I would get a kicker if you are not going duels. If you can afford this boat. Should be able to afford a 15 or 20 hp kicker. Plus the safety aspect of having an extra motor.
