[Charlie B]

Not a simple decision. Cost wise a single would most likely win out and if weight on the transome is a concern it is probably the lightest. Possibly the fastest and most fuel efficient. Twins would have the advantage in get you home reliability. Even more so if they have separate battery and fuel systems. They are said to have better maneuverability and if slow trolling is important can be run with one motor off. One other advantage is shallow water running. On a single the lower unit has to be below the deepest point on the bottom. With twins the motors are offset to a shallower part of the bottom and being smaller motors would have smaller lower units and props. There is another option. Big single with a smaller kicker motor. A good setup for slow trolling and to get you home if problems with main motor. Slowly but it will get you there. Not a simple decision but depends on how you want to use the boat...Charlie
