Why don't you come right out and say you're an idiot, instead of giving us
the numbers.

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. 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.

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?
