Volvo Penta folding propeller offers up to 1.5 knots higher
speed under sail compared with a fixed propeller. With no
complicated machinery or mechanisms to cause trouble, the
propellers provide superb reliability. The folding propellers are
manufactured from a nickel-aluminium-bronze alloy which
ensures excellent corrosion resistance.
2-BLADE FOLDING PROPELLER
Available for both sail drive and shaft. Propeller size has to be
calculated to match engine and gear ratio. Use calculation program
or propeller diagrams. For a complete propeller, order one blade kit
and one hub kit.

The folding propeller’s greatest advantage is itslow drag under sail. The
folding propellers offer outstanding manoeuvrability. Despite being a
folding propeller, reverse thrust is fully comparable with that of a fixed
propeller. The 3- and 4-blade propellers offer more or less the same
speed as a 3-blade fixed propeller across the full rev range. Upto 8
times lower drag compared to a 3-blade fixed propeller. And, what’s
more, the unique blade profile promotes an extremely quiet and
vibration free operation.
Water drag were measured in a test
carried out by SSPA Maritime Consulting.
Propellers mounted on S-drives were
measured. The lower drag produced by
the Volvo Penta folding propellers can
boost sailing speed by up to 1.5 knots.
