Folding propellers
The fact that a Volvo Penta folding propeller
offers up to 1.5 knots higher speed under sail
compared with a xed propeller will add greatly
to your sailing pleasure.
But also when cruising under engine
power, the high thrust make them stand out
from the competition. Thanks to the high
performance of the blades, even in reverse,
the propellers provide excellent maneuverability
in limited areas.
The patented elliptical profile (high skew)
of the propeller blades ensures effective,
low-noise operation with minimal vibrations
and no cavitation.
Since 2003, all Volvo Penta folding
propellers are made of a specially
developed, nickel-aluminum-
bronze alloy (nibral) to
minimize corrosion
and marine growth.
ENGINE ACCESSORIES
Secure reliability
Unclean diesel, water or microorganisms in the fuel can all cause your engine to stop or fail to start.
A pre-filter and a decontaminator are efficient ways to secure safe functionality – and reliability
– the whole sailing season, and seasons to come.
Diesel fuel decontaminator
Diesel fuels often contain microorganisms that
can start to grow and clog up the fuel system.
The fuel decontaminator solves this problem
permanently.
Lubrication, oil and coolant
Developed to meet the specific demands of
Volvo Penta marine engines and transmissions.
These products work perfectly in all operating
temperatures and maintain their qualities also
during long periods without use.
Extra alternator
Volvo Penta engines have alternators that
are perfectly matched to the torque of the
engine to provide extra charging without losing
maneuvering power. Upgrading with an extra
alternator will give high-capacity charging for
12 and 24 V systems.
Charging distributor
For efcient charging of multiple battery banks.
Power take-off
For powering auxiliary equipment. Adapted to
each engine series.
Tachometer
Provides analogue rpm readings and a digital
display for additional information.
Multi-information displays
The 4" display and 7" color display can show
a number of different data, depending on engine
model and sensors. Easy to customize menus.
The 7" display suits the D3 and D4.
Trip computer software
With the D3 and D4, full trip computer function
can be added – for information about fuel rate,
trip time, average fuel rate, and estimated
remaining time to empty.
NMEA 2000 interface
With the NMEA 2000 interface, it is possible to
obtain engine data in a compatible chart plotter.
Perfect to free up space.
Separate instruments
Available for voltage, fuel level, engine
temperature, alarms and more.
INSTRUMENTATION
Fuel pre-filter
Efficient pre-filters protect the
engine from water and particles.
They are easy to inspect and
clean for high reliability.
Maintain powerful charging
A sailboat often uses its engine only for short periods, but still consumes a lot of electricity.
For increased charging capacity, there are optimized solutions for all engines in the range.
