Outch, I managed to touch a rock when manuevering in a tight channel and I probably have a bent blade. The boat will be lifted on Monday and depending on the degree of damage I will either have it repaired or install a new one. In any case I will buy a set of spare props. Anyone know a good source to get a LH and RH pair of ZF/Rolla. The exact spec is:

ZF FPSW/ROLLA
39577/103
D750 P1050

The boat is a Ferretti480 with a pair of MAN 610
gear ratio is 1.92/1
 
Rolla props are not run of the mill stuff and certainly out of Steel Developments league.

I would contact Rolla in Switzerland for advice. ZF distributed Rolla for a while however they are actually owned by Twin Disc. ZF do own ZF Faster Propellers I wonder by designation FPSW it is Rolla manufactured by ZF Faster in South Korea under licence?
 
Txanks Latestarter for your reply. Strangely the port prop has more info stamped on it:

ZF - FPSW/ROLLA
39578/103
D750 P1050
E A.R.0.85
NR 8265

othervise the same but it has the aditional text/nrs:


E A.R.0.85
NR 8265

I will contact Rolla Switzerland for further clarification
 
Rolla use some real quirky patented blade forms, EAR dunno but if that is DAR (Disc Area Ratio) of .85 that is pretty aggressive. Rolla also use some exotic materials, however I doubt if they would share those with the Koreans.
