They start out with technical discussion of surface preparation but then wander off into all kinds of various metal working, which got me to wondering just who are these guys? Which lead to this:
DIY Boat Propeller - Part 5 - The Success
Casting is one of those things that kind of gets glossed over whenever people are talking about machinery. Conceptually simple, you just pour molten metal into a mold, let it cool, and presto, there's your part. In practice there are a whole lot of details that have to be dealt with. I am sure that somewhere else in their series of videos they explain where the pattern comes from.
This boat is under construction in Tulsa, Oklahoma, of all places. How are you going to get it to the ocean? I mean it is obviously a deep water boat. Turns out Tulsa has a port. (No way, dude!) No ocean going ships, but plenty of barge traffic, and the waterway connects to the Mississippi and so to the Gulf of Mexico and all the oceans of the world.

The Eastern USA is riddled with navigable waterways. The West Coast, no so much. I could not find a good map. This one is small and blurry. All the others either included some commercial distortion or were missing pieces. This one at least includes all the important parts.

The Tulsa Port of Catoosa (it's next to Catoosa, but it's barely inside Tulsa corporate limits) is a pretty impressive little shipping zone; there's an industrial park just adjacent, and two railroads come through.
If there's water, there ought to be a beach. We need a report.
