It's interesting to see that for full-size boats with a single propeller it is normal for it to be clockwise turning and yet for models it is common for it to be anti-clockwise.

Good video Ed. I can confirm the excessive air (ventilation) issue. Years ago I scratch design and built a towboat. I had a reverse thrust issue (boat barely moved in reverse) and noticed bubbles coming up the sides of the model. By placing a 3/4 inch addition to the transom I was able to eliminate the problem.

That is very interesting Ed.
My Sea Commander research has shown the boat to have excessive cavitation and possible blade “slippage” in the water.
Some research with propellers is already on my list of things to experiment with.
I would like to try a 3 bladed propeller, but my prop shaft is 5mm and I am having problems finding any 3 bladed props to fit it.
