I kinda like to think of the pitachable propellers as variable gearboxes, in inceasing the pitch you get lower rps engine side but higher thrust (rps/torque on a gearbox) on the output, it's just a matter of balancing it. Also I love how they kept the old propellers, this is how they should balance things to not scare beginners but give experianced players a challange
as soon as the pitchable propellers were released I got to work fitting and tsting them on my ship New M.S. Keltic, I set it up with a constant 1 and blade pitch on Keltic isnt yet changable, instead Ive used the sweet spot on the clutches, my configuration is 8 inline 8 3 by 3 modular engines, 2 5 bladed outboard propellers and 2 6 bladed inboard propellers, each propeller is powered by 2 engines, the top speed was 43 knots. Also the propellers are the medium ones. By the way, I built New M.S. Keltic in a modified workbench, she is a massive ship with 7 decks including the engine rooms, it requires a good computer to run as its potentially the biggest single piece ship in Stormworks with little to no spaces that arent accessable and decorated.
I remplaced 2 Azimuth Propellers (you know, the ones we're supposed to put on pivots) with a single Small Pitchable Propeller and gave it 8 blades. Not only did i get the same top speed as before, but i got much better acceleration too. You also dont need to add a gearbox for reverse, which saves space and that 5% torque penalty
These tests feel flawed when the engine sets the limit and never challenges the propeller itself. The tests would only satisfy me if you had an engine powerful enough for it to reach top speed before you reach throttle=1. In my understanding the text for the power rating on the propeller gives you some kind cap of force it can utilize. Whatever that means because it does not translate to any ingame value. But the source of the power is always the engine. You put 3 of these giant propellers on any of your ships but you would probably get a similar or better top speed if you would use less and smaller propellers geared at a higher ratio. Because propeller rps translate to speed. The only disadvantage I ever encountered with smaller propellers is that it takes a little longer to accelerate to top speed because you do not get this instant momentum which propels you out of the water. You even were half way there with the test of the small variable pitch propeller. The engine reved higher which means it got some spare power for higher rps on the propeller. Just one more gearbox and you can squeeze out 5 more knots. That said I highly appreciate your videos because they prime me with ideas. For example the momentum of the ships when you want to stop bugs me. Just bang in a PID in there with the speed times throttle and it makes you instant stop by the pitch angle when throttle=0. These propellers are not just a clutch and a reverser but also a brake. Splendid. Thumbs up!
ATP I don't really see why and how you can use the biggest patchable propeller it's just way way way too big for the 4-56m long ships we have if your going for looks the huge pitchable propeller is not the way imo

Pitch propellers are insanly useful, the ships I sail on utilize a diesel cruise engine and 2 gas turbines

Wdym 5% torque penalty?
gearboxes take some torque as "inneficiency" @@bradley9856
Man figures out that attack angle has impact on propeller performance 😆😆 aeronautics guys know that damn well
Bet they will be useful on steam ships where transmission already takes up a lot of space, and clutch doesn't make it any better
it seems the only real flaw with these is the naming sceme, same as the liquid fuel thrusters
Fun fact each propeller blade has its own hitbox and collision
Put a higher gear ratio to the propellers and slow throttle adjustment down for pitch can get higher speeds
negative pitch will let you reverse without a gearbox
