We have a 3 bladed Volvo folding Prop. that was fitted when the yacht ( Bav38 1991 ) was new.
It was rebuilt for the first time last winter by Darglow Engineering for about £350 and was returned with an 'as new' health report ( new oversized pins, blades/gears checked for De-zincing ( there wasn't any ) etc. ) 25 years and still going strong, not bad. I just change the anode annually.
So if your looking for trouble free and long service life, the Volvo is worth a look.
Volvo don't actually make them, I believe it's an Italian company but I may be wrong.
