Never a Gori prop again!

[JomsViking]

I'm a great fan of Gori (low drag), and my experience is that they are less prone to corrosion than many others - eating less zinc. I also know them as having EXTREMELY good customer service, but that could be due to the fact that we're from the same country.
But as others have stated poor maintenance hurts any boat or prop

As many have said, different marinas and waters can have widely different results on the zincs duration. I had an autoprop for 5 years, in 3 different marinas and its zinks (mine come with two, one bigger and a smaller one) always lasted a year, and were substituted more for prevention then for need. However, when I mounted the autoprop I have increased all the sizes of the zinks on the boat and later also increased the size of the smaller autoprop zink.

The OP says that the Gori comes with very small zinks. I never quite looked at the size of the Gori zinks, but if they are really small, that means that they have to be checked and changed more frequently.

I have an Autoprop on my Catalina 42. AB Marine had rebuilt the prop in 2007. In May of 2009 and 225 hours later a blade came off. Buntons Marine replaced the blade for $1500. I had it 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 for lost 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 product. In all their replies I feel like I am hearing from a politician trying not to give a straight answer.

Geez Nelson, how many times and places are you going to post that same thing? I think most people in the known world understand by now that you aren't a fan of Autoprop. By the way, we've had one on a boat for 18 years, no problems, and works great.
