VOLVO IPS PROPELLERS
We have carefully tested and chosen
the propellers to give your boat the
best possible performance and have
allowed for the additional weight in
equipment that might be added to
the boat.
Carry the necessary tools in order
to handle an emergency propeller change. Carry a set of
extra propellers and hardware. Always use genuine Volvo
replacement parts which can be ordered from your Regal
yacht dealer.
Many times a boater is cruising far from his mooring when
he needs emergency repairs. A facility may be able to sling
your vessel for propeller changing but may not have the
special hardware or correctly sized propellers for your
vessel. Be prepared!
Twin IPS drive vessel propellers are balanced to achieve
the highest performance standards along with running a
straight course with no power steering torque.
The IPS system features series a Nybral series propeller
system. As the name designates, the propellers are made
of nickel, bronze and aluminum. Identify the exact type
of Nybral propeller installed on your vessel so you can
carry an extra set for emergencies. Use the chapter 8 chart
as a guide but check the propellers themselves for exact
stamped type.

To check the propellers the vessel must be lifted using a
hoist with proper type slings that are specifi ed for larger
vessels. Make sure you read and understand the proper
procedures for slinging the vessel before attempting to
hoist your yacht. There are 2 sets of "sling" identifi cation
deck markers. The markers provide a safe lifting location
for sling straps. Make sure the slings used are wide enough
to support the boat weight.
After the propellers are removed they can be sent to a
propeller repair facility to check balance and recondition
the blades.
Also, the drive anodes can be checked/changed when the
yacht is out of the water. One anode is located on the drive
and the other anode is located on the transom. Use emery
paper to clean oxidized anodes not a wire brush.
A spare set of propellers can be installed while the original
set is being repaired. Refer to the Volvo IPS operation
manual for further detailed information regarding the
changing of propellers.
