Other Problems
Propeller Induced Vibration
Propeller induced vibration can be caused by inaccuracies in pitch, camber,
section shape and static or 2-plane imbalance. 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. Propeller Induced Cavitation and 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
may be 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.

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.
