Difficulties you may be having with your propeller:
Propeller
Induced Vibration:
Propeller
induced vibration can be caused by inaccuracies in pitch, camber
and section shape. Prop Scan allows us to see and remove these
inaccuracies. This results in a smoother, more efficient and
often faster propeller.
Tip Erosion:
Abrasives present
in the surroundings often cause tip erosion. Tip erosion reduces
the overall diameter and performance of your propeller.
Propeller Cavitation:
Propeller cavitation
causes vibration, noise and serious damage to your propeller.
Can it be avoided? Cavitation problems must be split into two
categories. 1 Propeller induced cavitation. 2 Vessel induced
cavitation i.e. cavitation caused by appendages, hull shape
and application. If the cavitation is propeller induced then
Prop Scan technicians can measure your propeller and show you
the cause of it.
Singing Propeller:
Some
propellers produce a high pitched noise at certain points between
idle speed and full RPM. At the best of times this can be annoying,
if this point lies spot in the middle of your cruising RPM it
will be intolerable. Prop Scan technicians have the solution.
Propeller induced
engine overload:
If you are the
proud owner of a beautiful yacht but you are a little embarrassed
about the black smoke that is emerging from its transom, then
it's time to do something about it. Overloading your engine
will vastly reduce the overall life of this engine.
Propeller not loading
the engine:
When an engine
revs higher than its recommended maximum RPM, it does not develop
its maximum Horsepower. In other words you are not using your
engine at its utmost capabilities. Most of the time this means
there is additional speed to be gained.
Fuel Consumption:
Does your boat
consume more fuel than the recommended amount? The reason for
greater fuel consumption is having a low classed propeller.
On average, an ISO
Class I propeller uses between 5-10% less fuel than a Class
III propeller!
Propellers not synchronized:
Many twin screw
vessels have badly synchronized propellers, in other words the
port and starboard engine are not loaded equally at maximum
RPM. This is caused by pitch, camber and section shape differences
between the two propellers.
Reversing problems:
Reversing qualities
are influenced by the position of your propeller and the section
shape on the suction side of your propeller. If there is a suction
section shape problem, technicians can locate it.
Poor propeller performance:
Poor propeller
performance can be caused by MANY different reasons. Incorrect
propeller selection, poor propeller accuracy etc. etc.. What
ever it is there is now a way to find it.
we
will measure, and provide a Prop Scan computer generated report
of your propeller Free
