Direction of props on a bilgepump does matter??

[zoomzky]

Hi!

Maybe a dumb question...

I decided for a Bilge pump thruster concept. 2 of them for forward/backward thrust

Want to use a Robbe 1471 RH which seems to be on backorder everywhere.
The Robbe 1472 is available but is a left-version

Does this matter?

Should i use one proptype(left/right) on each thruster??

Cheers!

Left or right's fine. One of each would be best.
