Hi guys need a little advice, I am finishing off a US Coast Guard Boat with twin props one left and one right handed, my question is if they are handed do the motors have to be wired up diferently i.e. One wired minus to plus and so on.

Simple answer is yes, you need to wire the motors so the props both rotate in the correct direction. I usually use a wetted finger behind (stern) the prop to feel the wash of air when rotating in the forward direction. if you can feel it from the front (bow) side it needs the wires swapping on that motor. I suggest you also check that the tx channel is set in the normal as against reverse setting before you start as some ESCs run slower in the reverse direction.
Hope this helps and if you find my post helpful please tick the like box as it helps others find the post

its a little safer to take props off and put a piece of masking tape over the ends of the prop shafts. That way you can check rotation directions and keep a full set of fingers ~laughs~

You could do as I did and bought a matched pair of handed motors😤👍😁
