I believe there's a generally accepted standard on golf ball mass and size limits - something like 4 cm diameter and some mass range equivalent to around 1.2-1.3 g/mL.

We will have to file an FAQ just to be sure though. anyone know when they will start answering the FAQs?

There are indeed competition standards for golf balls. If you purchase standard, commercially-available golf balls you should be fine.

I think that a buoy would be required. Moreover, I think that you could have a golf ball waterslide. The golf ball and a bit of water would flow over, and the water would be recycled into a lower container.

A new clarification has been posted regarding the golf ball:
Mission Possible - 10/5/18 (Division C) 4.b.iv. should read, edits in bold: Add water to a container to raise a standard, unmodified golf ball located in the same container at least 5 cm so that the golf ball rolls out of the top of the container and initiates the next action.

One possible way to use the least water would be to get a small section of 2" PVC pipe. Cut the exit end on something like a 45 degree bevel.
A float could be a piece of wood also cut on a bevel to force the golf ball to go where you want it to go. Since I have it, I would use a 1 3/4" hole saw to cut it our of a 2 x 4. Consider using poly urethane or a spray lacquer on it to waterproof it. Alternative is to microwave it for 1 min on high to dry it out. Caution, the wood will swell slightly from the water. Best to have 2 dry ones. By making it a little bit taller you could control the time by controlling the starting amount of water in the pipe.
Options for the wood could be a proper size plastic fish bobber or a large cork.

I like this idea. Its simple and seems hard to mess up at first glance at least

I have a simple solution but it might be problematic depending on what a container is.

Does the container for the golf ball have to be able to hold the ball through it's entire length. For example, could you have a narrower section connected to a wider section which holds the golf ball, with the entire apparatus being considered a container?

i see no reason why this wouldn't be allowed.

What are you guys using for the buoy? I've tried wood (pretty low density balsa) and 3D print material, but so far to no avail. Any ideas for materials?

Styrofoam works very well.
