Putting a LH prop on a RH setup engine would require running in reverse.
This will work on some engines/trannies, others will be destroyed by
constant running in reverse, and many will have a different gear ratio.

In any case, I think it would be noticeable on any modern setup.

If the shaft has a taper there is no way to put it on

of a RH prop or vice versa? Diameter and pitch could
be identical but it would be so slow if turning
direction were wrong.

Close Neal. Because of the taper fit, that won't work.

Care to elaborate on your answer?

Remove it, turn it around, put it back on.

You just bought a new boat and notice the prop is old and brittle.

You replace it with an identical prop. After motoring around for a
while you find the top speed of the boat is much lower, estimated to
be 2.5-3 knots and the prop seems to be slipping.

What is the most likely cause, explaination, and cure?
