Help needed choosing boat propellors & motors

Hello,
I’m making a prototype with ardupilot for a future project.
I need help choosing a combo of propellors and motors.

I’ve considered the blue robotics t200 propellors but it’s like $500+ for 2 not even including battery
Ideally the combo of motor, propellor, battery, esc is as cheap as reasonably possible. How small and cheap of electronics can I get away with to push a light boat?
I only need slow speeds of like >1m/s

Electronics I plan to use Pixhawk 2.4.8, M8n gps, 955mhz telemetry. + rc reciver + esc + battery

Thanks

look on ali express for thrusters, they have a few cheap ones.

I have never used any of them so I cant vouch for them.

I was looking at a kit of 2 green propellors and esc on ali express.
I’m afraid of the parts not working or instantly breaking , and since i’m sort of on time pressure, needing to order a new esc or something would suck

would this kind of thing work?

How long do you need them to last? If it’s just a few days in the water or just a couple of hours at a time, then they should be ok. but i wouldn’t send them out to sea.

oh thanks for adding links, i didnt see them.
I will get that kind of thing.
I dont need long range at all.

What kind of battery capacity should i be looking at for 20-30 minutes of runtime. The description on some of them is like 30A with 30-200W which is such a large range.

-edit:
some others say 12-24V but also say 300kV in the same title?

A 10ah 3s should keep you going for half an hour running full throttle the whole time but if your not in a hurry 5ah would probably be enough.

Great
Thanks for all the help!

KV does not mean kilo-Volts.

Personally I nearly always use the BlueRobotics thrusters and ESCs. They’re not the cheapest but they’re high quality.

I’ve used the green and red ones and they only lasted through one test at the end of which I beached the boat and the sand got into the thrusters and destroyed them. Very disappointing.

BlueRobotics is also a long time ArduPilot partner company which donates to AP and also make code contributions.
