Don, that cooper strip goes to the SSB turner in the aft locker then to the bronze plate on the keel.

Re: Vertical Batons
Just to balance this thread, I recently helped Kent Robertson sail "Kristy", his new-to-him SM#243, from Galveston to Key West. (You may recall his postings back in March & April). He had just installed new sails with vertical battens in the main.
Kent may want to weigh in here, too, but IMHO, the vertical battens were great. They furled flawlessly in heavy and light air and the sail was always beautifully shaped. No way to know definitively about added speed, but to an old racing skipper's eye they were the cat's meow. Certainly the point about potential furling problems is prefectly valid and a very conservative approach may argue against them - a few tenths of a knot, perhaps, vs. a higher comfort level, but, hey, that's why they make chocolate and vanilla - take your pick! Cheers, Craig Briggs - Santorin #68 "Sangaris" in Siracusa, Sicily

Jim,

As a sailmaker I am not enthused with vertical battens although there are some vocal proponents. There are issues with vertical battens getting stuck and causing problems. On a cruising boat you really don't want that risk. Has your sailmaker built sails for a SM before? I saw one SM where a sailmaker made the sail a bit too long on the luff and built patches that were bulky. The sail required several modifications to fit properly.

Re: [Amel] shaft driven alternator
Eric Lindholm
The transmission in my Maramu is a manual transmission, Hurth, which does not have a pump to lubricate the bearings. It is splash lubricated. You can free wheel it without concern. I think it is your hydraulic transmissions that have to be run every once in a while, as they do have a pump for pressure to the plates as well as the bearings. Same as a car. You can tow a manual trans car with no problems, not so with an automatic. Eric maramu 105

You cannot extract energy from the water in the form of a prop generator without creating friction. People can believe what they want to believe. The laws of physics and hydrodynamics will still apply. The only way to really reduce the prop drag penalty is with a feathering or folding prop which is precisely why the racing rules give credits for a fixed prop.

Re: [Amel] shaft driven alternator
Richard Piller <richard03801@...>
Guys, the one point you are missing is that the Maramu transmission is designed to allow for free wheeling. NOT all transmissions are. Before anyone with a SM takes to sea with the prop turning undersail please take a look at the spec on YOUR transmission to be sure you can safely free wheel. Regarding the speed of the boat; we did several trans-Atlantic crossings with the prop on our Maramu free wheeling and charging the batteries that worked better then the wind mill we have on our SM. The fact is that in practice the free wheeling/charging solution is the better way to go..Best to all, Challenge in Annapolis SM 209Richard and Joan

Bilge pump gear
btleonore <leonorebt@...>
Hello fellow Amel owners
I had my bilge pump fail due to a nylon gear losing a tooth or two. It is designed to fail to protect the rest of the pump system. If any one has an old pump with the worm driven gear intact, I would like to buy the gear from you. With or without the shaft on which it is mounted. I had an old pump fail due to the drive shaft breaking and had to replace the whole unit. That was proper but to replace a whole pump for the failure of a part designed to fail does not make sense. Motor, valves etc are fine. I would like the name of the manufacturer, if you know also, for contact purposes. Any suggestions in addition would be appreciated. Thanks, Bill on Leonore of Sark, SM 72 PS. After 12 years of sailing, Trudy and I are selling Leonore. If you know anyone who can not live without an amel, let us know. Thanks.

Re: [Amel] Re: URGENT Help Needed - RPM Issues

I don't know if anyone suggested it yet, but I would install a pressure gauge on the intake manifold to read the boost pressure. With that and a pyro, you can usually isolate any type of problem. Eric maramu 105

I agree with all that has been said in reply to your problem. I would also check the following: Remove the "actuating rod" that goes from the vacuum pot that is connected to the small arm on the top of the turbo. This arm goes to a shaft that operates the valve that regulates (the wastegate) the pressure (boost) that the turbo can produce. This shaft "cokes up" and can freeze in the open position causing the boost from the turbo to exit the chamber and go out the exhaust, no boost no RPM. It is also possible that someone has put a small crescent wrench on the flat arm and tried to work it back and forth to free it up. This may work, but it may also cause the small weld between the shaft and the flat are to break (very hard to see with naked eye) If this happens then everything will look like it is working, but in fact the arm is moving and the shaft is not, causing the same problem, wastegate stuck in the open position. Final thought. It seems that when Perkins, Volvo, GM who ever, asked Garret to supply the turbo they insisted that no parts be sold at retail. The dealers will be happy to sell you a complete turbo, but not the individual parts. My personal rant.
