- 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. Bring
in your propellers for a free examination, we will need information
from your vessel performance form.
- Tip
Erosion
Abrasives present in the surroundings
often cause tip erosion. Tip erosion reduces the overall diameter
and performance of your propeller. Come and visit us, bring your
propeller and your vessels performance form with you and we will
show you how we will restore your propeller to better than new.
- 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 we can measure
your propeller using the Prop Scan inspection system and show
you the cause of it. What do we need? We need your propeller and
your vessel performance form to complete your free propeller assessment.
- 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. Help is
at hand.
We will need your propeller and your vessel performance form,
with this information we will be able to remove the noise from
your propeller.
- 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 and the black smoke can seriously affect your boating
pleasure.
You don’t have to put up with
it anymore. Bring in your propellers along with your vessel performance
form and we will tell you, with no obligation to you, what needs
to be done to overcome your problem.
- 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.
How much can we gain? Let us provide you with a free assessment.
We will need your propeller and your vessel performance form
to complete your inspection.
- Propellers
not synchronized
Many twin screw vessels have badly
synchronized propellers in other words the port and starboard
engine are not loaded equally at equal RPM. This is caused by
pitch, camber and section shape differences between the two propellers.
Can it be resolved? You can bring in your propellers and we will
show you what the difference is between the port and the starboard
propeller. At the same time we will advise you, at no cost to
you, what it takes to resolve your propeller problem. We
also require a completed vessel performance form to complete your
propeller analysis.
- 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, Prop Scan will locate it! Let us scan your propeller,
free of charge, and show you how we propose to resolve your problem.
- Excessive
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!
- 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 we will help
you find it. Complete the vessel performance form, take your propeller
and come and visit the closest Prop Scan shop to you. We will
assess your propeller at no charge to you and give you our professional
opinion on how his problem can be resolved.
- Other
Problems
There are many more propeller problems
that we could address on this site, if you suffer a problem not
mentioned on this page, contact your nearest Prop Scan shop.
