cheers for posting that.i notice Steel developments are in the credits.i had a lot of trouble with the well known propeller people.I was told about steel developments and they were only down the rd from me,previous to that they had been half way round the country.most wanted to make me 4 blade which i didnt want.i ended up at S/D who told me mine were scrap as they had been repaired using the wrong material.this was true and had not long been done.they made me two new three blade to the original spec.i cant praise them enough ,at the time i had a deadline to be in the water to help marshall the round island and Cowes Torquay.I have no connection with this company just a very happy punter.
