Folding propellers are being used more and more on sailboats. There are several makes to
choose from for conventional installation.
The most important advantage with a folding propeller is that it gives less current resistance
during sailing but when the engine is running it has a somewhat lower effect especially when
manoeuvering astern.
If the boat is supplied with a folding propeller it is important to know about and observe the
following:
Putting in "FORWARD" should take place during idling. Changing at higher r.p.m. can damage
the propeller because of the great stress resulting when the blades are folded out.
When the boat is to be laid up the propeller should be treated as follows:
Clean the propeller with fresh water, remove the screws for the propeller blades' suspension
pins, take away the pins and the blades. Clean all surfaces and then lubricate all the propeller
parts with grease. Take special care with the bearing surfaces on pins and blades. Protect the
propeller boss.
When launching:
Fit the propeller together, wipe off superfluous grease and check that the blades fold inwards
and outwards easily.
