Haha, not what you're thinking sorry. This is a propeller test for my outboard engine, BUT.... there are some nice drone shots in there.
Which Propeller has the best output, in this video I find out. Late 2019 I brought a new Tohatsu 9.8hp 2 stroke engine for my dingy. It came with no spare parts so while in Europe I ordered amount other things a spare propeller. I ordered it in a slightly different dimension than the original so decided to find out which was more suited to our situation. We did some back to back timed tests and ended up with a pretty accurate if unscientific result.
Enjoy!
