[Amel Yacht Owners] I had a defective prop
|
Aha!!! More evidence that my old Volvo 78 HP with the bigger AutoProp was over propped! I couldn't get Bruntons to put it in writing, but that's what they told me verbally. I still have the prop that came on the boat serial no. AP2735LH If anyone is interested I'll be happy to sell it for a good price.

Thanks for the update. Our old prop is on the recall list. We are contacting AB Marine in RI. On a further note we upgraded the engine to a 100HP Yanmar from 75HP and were advised by Autoprop we had to replace our H6 prop with a larger diameter prop as it would not work with the 100HP. They further stated that the they had advised AMEL of this on numerous occasions and AMEL would not increase the size to accommodate the larger HP engines. When we asked at AMEL they stated that they knew the vessel better than Brutons. We changed as Yanmar would not warranty the engine without the changed prop. Haven't done a comparison in props since the change. Maybe one day when we have to repair/rebuild the current prop.

To perhaps bracket the SM hull #'s with potential exposure to this defect,
Aletes, hull #240, laid up in 1999 has Autoprop #AP2665, apparently manufactured prior to this issue. Mike Ondra From: amelyachtowners@...

Fair Winds Eric Kimberlite Amel Super Maramu #376 Autoprop Issues Recall Brunton's Propellers is initiating a product recall, as a precautionary measure, based on customer reports and in-house technical inspection. Their recall letter follows:The recall is necessary because of a small number of instances where, through lack of maintenance or poor assembly, blades on early propellers have become loose. Premature wear to the blade mechanism may, in an exceptional circumstance, result in the blade working loose. Using the Autoprop under such conditions over long periods of time may lead to potential breakdown of the locking washer securing the blade to the hub. This situation will only occur on certain size Autoprops with a serial number between AP2902 and AP5299, purchased between 9/9/98 and 1/1/02. Please check whether your Autoprop falls within this range. The number appears on the palm of the blade. If it does, contact your local dealer or the autoprop office in England. We can confirm whether your Autoprop is affected or not. As part of our ongoing product development plan, to enhance performance and ease maintenance, a new blade locking mechanism has been introduced. This mechanism is now being fitted to all roller bearing style Autoprops. Brunton's Propellers intends to take the following steps to address this situation: 1. Modification of the bearing retaining and locking mechanism. 2. Free upgrade to new style locking mechanism for all Autoprop user covered under our warranty policy. 3. New generation lip seal fitted free of charge with all upgrades. 4. Worldwide support network of dealers and service agents for local assistance and advice. We appreciate the difficulty in assessing this situation, particularly if your yacht is afloat. If your Autoprop does need technical attention related to this recall, we will endeavour to make arrangements to upgrade it with minimum disruption to your sailing schedule. If you would like further clarification, or to talk about how any of the above points may affect you, please contact our head office on 44(0) 1225 427511, service@..., or your local Autoprop dealer.

Subject: Re: [Amel Yacht Owners] Bad Vibration in the prop drive shaft Bill, One more thing. I am fairly sure that AutoProp is undersized for that engine. At some point that boat was repowered. An AutoProp H6 would be appropriate for a 110hp engine. I have known other SMs to keep the undersized propeller, but do not know their experience positive or negative.

Paul, Is it possible that you are mistaken? I am fairly certain that your boat with the 75hp came with the H5. BeBe #387 (very close to yours and Eric's came with a H6, but BeBe was built with a 100hp Yanmar. I am fairly sure that the 75hp came with a H5. And, I would think that Amel would know more about the requirements than Bruntons. I am guessing that Bruntons has very little experience with a keel, hull, and propeller shaft design that Amel uses.
