WildCat Propellers has invested heavily in the most sophisticated
computerized Prop Scan Inspection Systems available
in the marine industry today.
Our Senior Technicians have attended Propeller Dynamic’s
Advanced Propeller School and have been educated and certified
to a level that conforms to the US Navy Standards.
With our three Prop Scan units we are capable
of measuring propellers as small as 5” up to 134” with
as many as seven (7) blades. Today’s complicated and sophisticated
propellers can not be acceptably repaired with Traditional Equipment.
Propeller Dynamic’s Windows based Prop Scan EPS software allows
our technicians to quickly measure and evaluate modern propellers.
Prop Scan EPS – Enhanced Propeller
Standards is used in the
propeller repair and modification process and has been created to
further enhance the well respected International ISO 484
Standards.
The ISO 484 Standards were created prior to the modern computer technology
and more importantly the sophisticated Prop Scan marine propeller
inspection system.
Now your current propeller or an “off the shelf” propeller
can be tailored to suit your particular boat and motor combination,
maximizing vessel performance.
If your propeller is damaged or vibrating, if the engine RPM’s are not
correct, or just sluggish; WildCat Propellers can correct the problem! In addition
we can introduce the latest design features into your propellers.
Introduction of these design features will maximize the efficiency of your propellers,
yielding extra speed, increased fuel economy, smoother running, and quieter propellers.
The
traditional crude propeller is converted into a sophisticated device that compliments
both your engine and vessel.
PROP SCAN Dealing with
Vibration

SCAN NEWS
“ As
you are aware we commenced using Prop Scan exclusively
for our propeller repair work some four (4) years
ago. The majority of our fleet has now been slipped
and the propellers brought to Class 1 Standards.
The information we have been able to gather is very
encouraging to say the least. Fuel savings have been
on the order of 20-30% as well as a marked decrease
in hull vibration has been experienced on most of
our vessels.”

A boat should not vibrate. Vibration is a sign
of inefficiency, not only is it annoying, it can damage the engine
or transmission, and
it robs horsepower from the engines. Our experience shows that a
majority of vibration on a vessel is propeller related.
Weight Imbalance - simple to fix.
Pitch Imbalance is more difficult.
If one or more blades
are higher in pitch relative to the other blades they will induce
asymmetrical
thrust resulting in a vibration problem. This is most often felt
as vibration at a certain specific RPM. The propeller induces a whip
in the shaft which is most noticeable when the RPM’s reaches
the shaft’s harmonic speed.
Hydrodynamic Imbalance
This
is the most difficult. This requires measuring
equipment not only capable of displaying the hydrodynamic shape but
a Technician qualified to interpret both simple and complex propeller
designs. Hydrodynamic imbalance can cause vibration throughout the
entire RPM range even if the propeller has been statically balanced
correctly.
Our Prop Scan technicians are Trained and Certified to deal with
these problems.
