I have an Autoprop. AB Marine
had rebuilt the prop in 2007. In May of 2009 and 225 hours later a blade came off. I sent it to AB Marine
who sent it Buntons Marine in England
. Buntons Marine replaced the blade for $1500. I had the prop lubricated every six months. I am always in deep water. It never touched anything but saltwater. I only go to Catalina
and back. Other than the lost
blade there was not any evidence of damage or distress
At the time Steve Armitage of AB Marine told me that losing a blade was a “rare occurrence” and that he did not have an explanation for why the blade fell off. David Sheppard of Brunton's Propellers Ltd, told me losing a blade is an “an exceptional case”. Contrary to their comments the prop has been subject to a recall
blades. If you search other support groups and blogs you will find many others that have lost Autoprop blades. It demeans their credibility to say otherwise.
Although I enjoy the performance of my Autoprop my experience with AB Marine and Brunton's Propellers has been extremely disappointing. They are unwilling to stand behind their expensive product. In all their replies I feel like I am hearing from a politician trying to avoid giving a straight answer. I would stay away from anything that might need to be serviced by AB Marine or Buntons Marine (Varifold, Autoprop, Gori).
