Boat propellers?

[Louis93]

Hey guys so i've made a boat and since we've now got the heli rotors i'm set on making the engine work using propellers, the only issue is... I can't get it to work!!!  I've tried several designs and the most success I've had is 2 'wheels' made of wing surfaces rotating in opposite directions which gave me a whopping... 0.6 m/s, anything else i've tried has either been worse than that or not moved me at all. Wondering if anyone else has got any working propeller designs they wish to share?

I got a prop-driven submarine up to 13 m/s, although that was a while back, before the stock propeller and fan blades. I haven't tried to use them underwater yet.

from what i've noticed, the actual propellers haven't got a big enough surface area to push you although I could be wrong... and that is actually a nice submarine, 13 m/s is something i'd be happy with lol, I might try recreate that design into my boat, maybe add some propellers to the front

I just checked and the actual propeller blades don't seem to do much underwater. The small elevon though is super effective, I got a sub well past 20 m/s on them.
