Answer 1

Build a Tesla Turbine Engine (300 Hp) which is no bigger than a man’s hat.

go to: http://www.fuellesspower.com/tesla.html --- The Tesla Turbine

This engine can fit into the palm of your hand and can produce 300 Hp at 2,000 rpm’s! It is powered by air or compressed steam.

This engine can be easy to build and geared down to power a home generator or a car or an electric car. We know that this can be an over unity Engine with as much free energy as you will ever need.

Included is info on a company that builds them and how you can contact them.

Medium Boat? Are we talking Toy or Real? 1' or 20' (1-7 meters)? You actually mean "Build"? Drill and Metal Lathe stuff?
The gas engine on Airplanes and Boats are of simple design and work on the principle of a 2-stroke (Cox for example). The throttle is easy adjust with a remote.
If the boat bigger use something like a weed-eater engine.
If, you know enough to build the two above should be easy. Just look how they made.
I try to find some information, so, I will add as I find.
Here a Steam Engine and should be an easy build. I would have to think on giving it a Variable Speed. It may be able to be controlled easy by steam pressure.

There is no way to tell you exactly what you will need. Each make of engine will be unique in some way. What is important is that you buy quality tools. Get the basics and as you need more add to the set. I am sure that Sear's makes a basic mechanic's set that will get you going. Also most repair/shop manuals list needed tools for the job. Manuals are as important as the tools to do it right. You can invest a lot in manuals but you can't work without them.
