La flex o fold mi ha risposto e ha confermato il mio sospetto cioè corrosione dovuta alla corrente di banchina, infatti mi sono ricordato che quando 2 anni fa ho acquistato la barca e sono andato a vederla a Caorle il precedente armatore per non perdere l'abitudine di buon ex motoscafaro la teneva sempre con la corrente di banchina attaccata, alla mia domanda del perché la tenesse sempre collegata si era anche stupito come per dire "che male c'è" .....
Questa è la risposta della Flex-o-fold danese:
Hi all,
I'm an Italian customer and owner of a 2008 beneteau first 45 with yanmar of 54 hp and sail drive sd50 and a 18 inches 3 blade left flex-o-fold propeller. The boat has a f-o-f since first day and now She has about 700 engine hours. During my last maintenance job I discovered many micro craters above surface of the blades in both side as showed in attach picture, could you explain me the origin of these craters? What can I do?
Let me know if you need other informations
Regards
Dear Marcello
have you had your boat onto shore power? As it seems like you have had a small hit of electrolysis (would explain the small craters), but it wouldn’t make any differences in performance of the prop/blades – you just need to make sure it won’t repeat again.

....abbiamo fatto tante discussioni sulla corrente di banchina attaccata (io sono contrario..) e paradossalmente senza averne colpa ci sono incappato .
