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.
Bring
your propellers in and we will
measure, and generate a Prop Scan

propeller free
