Hi thewildernessvoice,
If you want to stick with 24V to protect your inverter investment, you've got a few options. You could install a small inboard system, but if you boat is not already equipped with a shaftlog, that's a tougher conversion. If you boat has only had outboards to date, then I would stick with that format.
You could convert an ICE outboard to electric, using the same kind of motor, controller and batteries. You might be able to hook an electric motor directly to the outboard drive leg, but sometimes a set of belts and pulleys to match the motor RPM to the prop is in order, Alternatively, you can change the prop. Some people will cut the anti-ventilation plate to get extra clearance for bigger props.
Like you said, another option is using a trolling motor, but they are typically set up for high thrust and slow speed (around 3kts). There are also a number of retail electric outboards, you can find a variety of choices with a simple search. If you go this route, I believe that the Torqeedo outboards are the most efficient small electric outboards available. They are pricey, but this will probably get your conversion dane with less work than other options. With such a short waterline, the Torqeedo Cruise 2.0 should drive your boat to hull speed and works with a 24V system. your range would depend on the size of your installed traction batteries.
But you have a number of options, everyone here might have their own idea of what is the best choice for your boat, but the final choice is yours. It's you money, your time and your boat. Yo get to pick what sounds best to you.
Fair winds,
