Operation & Servicing
The VARIPROFILE feathers automatically when the shaft rotation is stopped. After engine start-up and shifting into gear the
blades will engage in either forward or reverse.
THE BEST WAY TO FEATHER THE PROPELLER IN THE SAILPOSITION IS:
VARIPROFILE sailposition with
mechanical gear-box:
»
Power at 2 to 3 knots in forward.
»
Stop the engine and engage the transmission in
reverse to stop the freewheeling of the shaft.
VARIPROFILE sailposition with
hydraulic transmission:
»
Power at 3 to 4 knots in forward.
»
Stop the engine while still engaged in forward.
The remaining oil pressure of the transmission
will stop spinning the shaft to feather the blades
in the sailposition.
If the propeller is not feathered in the sailposition the shaft will freewheel like with a fixed propeller. In that case start the
engine again and repeat the steps above. Once the prop is feathered , you may remain in gear or shift into neutral.
DO NOT stop the engine while it turns in reverse. In this case the blades will stay in the reverse position and will not feather.
You can actually use this feature to drive a shaft generator.
TROUBLE SHOOTING: If the propeller does not work in forward or reverse go systematically through the points below:
»
Check low idle of the engine. It should be 900 to 1000
rpm in idle.
»
Check shifting movement of the transmission lever.
Make sure that the shifting travel is not too short. The
amount of lever travel, as measured at the pivot point of
the actuating lever, between the neutral position and end
positions for forward and reverse can be found in the
owners manual of your transmission. A larger amount of
lever travel is in no way detrimental.
»
Check the clutch discs of the transmission. They could
be worn out.

WARNING: It is important to follow the instructions below
carefully so as to avoid excessive load and shock to the
gears, shortening their life.
»
When going from ahead to astern or the opposite, it is
necessary to idle down and shift at low rpm’s (max
.1200rpm) between gears to allow smooth reversing of
rotation without binding. This will substantially length-
en the service life of your propeller gears.
»
When going from ahead to astern or the opposite, you
can hear the turning-noise of the feathering blades.
This is normal and not a problem or a defect of your
VARIPROFILE.
»
The propeller body must always be completely filled
with a high viscosity grease. We recommend synthetic
grease typ TW.2 GEL or mineral multi-purpose grease
EP/SAL
»
The propeller must be protected from electrolytic cor-
rosion by fitting the usual zinc anodes on the shaft plus
the prop anode. We recommend the replacement of the
anode once a year.
»
If you want to protect your VARIPROFILE with Antifoul-
ing, use only Antifouling which needs a primer first.
Otherwise chemical interaction and decomposition
could occur. Our recommendation is Velox TF plus
including a primer ( offers also protection against elec-
trolyses ), available from your VARIPROFILE distributor.
Never dismantle the VARIPROFILE yourself!
Disassembly and reassembly require special tools and technical know-how only available at the factory
or their approved service centres.
SERVICING
The VARIPROFILE needs to be greased a minimum of once a year with the
special EP/SAL lubricant available from your VARIPROFILE dealer. The VARIPRO-
FILE body should always be completely filled with a high viscosity grease of a
hydrophobic nature. Remove the cap screw and screw in the lubricating nipple
which is supplied with the tools. Further remove the zinc anode! With each pump
of the grease gun rotate the propeller from forward stop to reverse stop to allow
the grease to work through the propeller. Stop to pump when enough grease
comes out of the anode drill hole on top of the prop (Fig.1).
Factory supplied special grease EP/SAL is recommended and available from
your VARIPROFILE distributor. Avoid regular white grease (sterntube-grease ) !
