Hi Adam,
I've got a Duffy 18. It's basically a floating golf cart. It uses a GE motor and Curtis controller. Exactly what you want to do. VERY simple setup! My advice would be to find a used, working golf cart for sale. Then you've got the motor, controller, fwd/rev switch, speed potentiometer, wiring, battery cables and the most expensive parts... the batteries!
Make sure to check the batteries' specific gravity if they are the flooded type (removable caps on top for adding distilled water) so you know that they are in good condition (Google how to do this and make sure you compensate for temperature).
You'll see how it all comes together on the cart and apply it to your tug. Try to find one that includes the charger. You'll also want to get a de-sulfating maintainer to increase battery life. A good one of these will tell you if you have good batteries. Then part out the rest of the cart on eBay.
There's schematics and YouTube videos all over the net showing what you want to do. Videos are mostly people working with cars.
If you can build the boat, you certainly can add the electric running gear! And make sure to leave room on the cabin top for solar panels later on down the road.
While I'm at it... Any electric boaters on this list in the Detroit, MI area?

I am in the planning stage of building a wooden 14' mini tug boat powered by an electric (golf cart) motor. The plans that I have go into motors, controllers, solenoids, etc. and I was hoping that someone would be able to simplify it and point me in the right direction as to what exactly are the components I need to purchase. One person who built a similar boat used: Advanced DC #A89-4001 Motor, 6HP/36-72VDC and a Curtis-PMC #1205-201 Motor Controller, 36-48VDC/350A but I really don't understand what that all means. I also have questions about what you use to give it more power (to increase the speed) or but it in reverse, etc. I appreciate any insight. Thank you! Adam
