Not unless you have a geared engine, but even in that case, seldom does that have any bearing on the propeller...which isn't a gearbox. It can be thought of somewhat like a transmission, but even that is overcomplication.
To be even more pedantic it should probably be compared with the DAF Variomatic gearbox from the 1970/80s. Never drove one myself, but an ex-girlfriend of mine used to have one and it seemed to be a constant rev, variable speed machine.
On the practical side, as the revs are constant, you will have to get used to setting your power by manifold pressure. Should take all of at least 30minutes!!!
