On our Mahe 36 2008 (sold last year) I have had the Volvo penta
folding props as Fountaine Pajot
installs as option.
I found these to have correct pitch
for the boat. However you will find some discussions on one of the other Mahe threads of the forum about the correct pitch
. You can find the other threads, among them about the propellers, through the Mahe 36 tag of the cruisers forum.
The Volvo Penta folding props are OK, with the following remarks:
- They are expensive
- The hinges wear out. On our present boat there is some play after 12 years. But a friends catana
has totally worn out props (4 blade folding Volvo pentas) after 7 years / 2500 engine
- The propeller
anodes (3-piece ring anodes) dissolve in 6-8 months in the water
, while the saildrive
anode lasts a few years. If you lift
your boat every winter this is just a financial issue. If you are long-term cruising you need to have them on stock and install them under water
which is doable, but not nice outside the tropics! Especially when you need to replace it in the winter in the water. (Maybe the fast wear of the prop anodes increases lifetime of the saildrive
- I experienced a short 10 mm rope
from a fishing
net stuck between the saildrive and the propeller
. This damaged the hub of the propeller, it became excentric and caused vibrations. The propeller hub has a central stainless steel
bush with splines. This is attached to the outside bronze cylinder by a rubbery plastic which is maybe cast in? This plastic was distorted, causing the excentricity. The stroke of the excentricity was around 1-2 mm on each side.
- Advantage of the Volvo's is of course that they fit nicely on the saildrive. And the bronze has some (limited) anti-barnacle protection, but still you will experience barnacles
Seeing the above I would consider not to take the volvo penta's, there are many other types.
In no case I would take props with fixed blades, unless you are the motorsailing type of owner using the sails
to provide shadow (-;
I hope this is useful for you.
Allow me my curiosity: Why do you need to replace the props?
