Dynamic Balancing is often used to mask propeller
problems It is critical that any rotating object,
such as a propeller or the tire on a car be balanced.
If not properly balanced the resulting vibration could
cause serious damage to the drive train or the vehicle/vessel.
Dynamic Propeller Balancing is done on a single
plane. In the process weight is removed from the heavier blade(s)
until the propeller is dynamically balanced. This process compensates
for any weight problems associated with the boss (hub) and any loading
problems associated with mismatched pitches between blades. Mismatched
propeller blade pitch creates a situation where the propeller blades
are unevenly loaded by air pressure as the propeller is spun.
The dynamic balancer senses this mismatched loading as
an out of balance situation. This is then compensated for by the operator
by removing weight from the blades until the Dynamic Balancer is “fooled”
into thinking the propeller is balanced.
Dynamic
Balancing
In the water the load on the propeller blades is proportional
to the load created by air on the dynamic balancer out of the water.
In other words a propeller that is dynamically balanced will probably
run smoothly in the water. If there is a pitch problem dynamically
balancing a propeller will mask that problem.
A
Pitch Imbalance problem will compromise the efficiency of
a propeller which in turn compromises the efficiency of the vessel
To properly dynamic balance a propeller it is imperative that the
static balance also be checked after dynamic balancing. If after dynamic
balancing the static balance is out it is an indication that there
are existing pitch balance problems. A propeller that is correctly
pitch balanced and then correctly static balanced will be dynamically
balanced.
On a correctly repaired and static balanced propeller that is ISO
Class 1 or better dynamic balancing is redundant.

Your team did a fantastic job. We got them on with the prop speed about
10 days ago, and dropped the boat in the water last Thursday for the run
back around to Rudee. With a clean bottom and the new props we picked up
1.5 knots at both cruise and top end!! The boat bounced 35 knots at 3050
rpm/98 % load. Top speed prior when I picked the boat up new from the factory
was 33.5 knots. What I really like is the cruise, better speed, fewer rpms,
smaller fuel burn….. How can I go wrong? And we didn’t have
to use the tabs. I can’t wait to see how they work in the blue water.
Thanks for all of your insight and for asking the right questions.
Sincerely,
