One has to live in the real world. Especially these
days. When somebody uses the word 'identical'
a smart person realizes an identical in every way
prop would behave the same as the original.
Therefore one must conclude the prop was not
identical provided it was not installed backwards.
Backwards installation was my original answer which
was made impossible with the inclusion of the information
on a tapered shaft. Therefore, using logic, the only
answer was 'identical' was not identical.
Brilliant minds always consider real world situations
and do not rely on strict definitions of words most
people use very loosely. Savvy?

You're just upset because I'm so brilliant and
you're not. Even though I am a sailor, I know
more about motors and gears than the average
bear.
I have to dis-agree.
Idential is not a counter rotating prop.
If he said identical pitch then perhaps. But he did not.
Can you not understand a question?
RH RH = identical
LH LH = identical
LH RH is not
RH LH is not
Please look the word "Identical" in the dictionary.
The only one who had, the only proper answer, was me.
A missing woodruff key is the only proper answer to Barts question,
besides the transmission bands slipping. THATS IT.

When one has an IQ, measured by several
different professionally administered tests, in
the 148 to 155 range, things that most people
have to think long and hard about just seem
to be immediately available in my brain without
even giving them much thought.
This is perhaps why I have so little patience with
liberals. To be a liberal is to be stupid. There
is no other explanation.

5 points to Neal.
Inboard diesel powered boats commonly have different
gearing in reverse.
Incorrectly installing a RH or LH pitched prop when
the opposite was called for could cause a boat to
run at slower than expected speeds, albeit it would
move forward in the reverse position and vice versa.
Neal immediately grasped that the gear ratio might be
wrong and this could be explained by the boat running
in reverse, and at a lower gear ratio.
And you said identical. Identical is not a diffrent rotating prop.
To much rum Bart? WTF.... you usually do much better than this.
Sheeeeeze

If the shaft has a taper there is no way to put it on
backwards so, perhaps, they shipped a LH prop instead
of a RH prop or vice versa? Diameter and pitch could
be identical but it would be so slow if turning
direction were wrong.

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?
