Some thoughts on Volvo-Autoprop issues
rbenven44 <no_reply@...>
Hi,
A couple of years ago, I posted my experiences with the Volvo RPM issue, but I'll repeat them now to address the recent questions. I have SM #195, 1997 model, with Volvo Penta TMD22 and Autoprop. In July 2002, while in the Azores, I found the engine not giving me full power. I had the injectors cleaned, but still could not get over 2100 RPM. Cleaning the prop did not help (I have a Brownie's Third Lung, and spent a lot of time underwater cleaning the prop to a fine polish!) In September, in Lanzarote, I removed the turbocharger (very easy) and took it to a diesel car mechanic in Arecife. He cleaned the substantial carbon deposits from the "hot" side (the turbine that is powered by exhaust gases). Cost was 60 Euros. I immediately was able to get 2800 RPM underway, and speed increased from 7 kts. to 8.6 kts. My theory is that substantial motoring at 2000 RPM or less (to get good fuel economy) leads to this problem. The turbo is designed to boost power at high RPMs, and the engine needs to be run at full power from time to time to use the turbo and "burn off" the carbon in the turbine. Amel recommended this to me when I bought the boat, but the thought of running the engine flat out for 5 minutes at a time scared me. I now do it at least once a month, and still get full power, even with a dirty prop. For those of you with Volvos not getting full power or full RPMs, clean your props, but also clean your turbos. It's very easy to do, and I'm sure you'll see results. Roy on Excalibur SM #195

Re: [Amel Yacht Owners] Speed vs. RPM
Ag Av8ter
Hello Claude,
I spoke with a man in Ft. Lauderdale when I had our boat hauled out for her survey. He owns an older Amel, not sure what model. He suggested that as long as the boat was out of the water, that I apply "some stuff" (I do not remember what it is called)> Evidently it is a coating or film that goes on a squeaky clean prop an seals it. Thus it is less apt to fouling and easier to clean when fouled. I am an aviator, and there are "tapes" to cover the leading edges of the wing and prop to accomplish this same thing. And for rotorcraft it also reduces the leading edge errosion. When I get back to my boat, in just a few days, I will try the full astern to see what kind of RPM she will turn. In my particular case I am convinced that the boat is over pitched, and that I am not getting optimum performance from the turbo. (Low RPM, low to ineffective turbine speed, thus increasing coking or carbon build up) Tony Gray WORLD CITIZEN SM #266 --- In amelyachtowners@yahoogroups.com, Claude Roessiger <nearlynothing@...> wrote:

Re: [Amel Yacht Owners] Speed vs. RPM
Claude Roessiger <nearlynothing@...>
I have had no end of trouble with this combination.
Amel aren't playing this straight with us. Every owner I have met with the Volvo-Auto prop combination has similar woes. I think the source of the trouble is the prop. In reverse, do you get 3500 RPM? If so, it says a lot. This darned prop (and I have had unsatisfactory exchanges with Bruntons, the maker) is unbelievably sensitive. Unless it's polished to perfection, it seems to just not give power. Expensive as it is, I think to change it. At full power the SM ought to give you 8 kts +. I have had similar woes in waves as you describe, no power, no speed. The Volvo turbo-diesel is itself less torquey than a straight old diesel as in the old Maramus, bullet-proof engines. This said, an 80 hp engine should do the job. I think the prop is suspect. If anyone has made a prop change successfully, it would be good to know.

Yet another way of dealing w/ fuel
Ag Av8ter
There was not long ago a SM2000 that was near us in Trellis Bay. I
can not remember her name. Her skipper was really a neat guy and showed me little "Amel" things on my boat. What he did as a way of providing clean fuel in an "all of a sudden got dirty fuel situation" was to have another fuel line added to the after tank inspection cover. Just a tube welded in place that is "several" inches from the bottom of the tank. The "new" line is tee'd to the original and has two block valves. This gives him the option of using the original Amel fuel supply, or picking the fuel up away from the bottom of the tank at his option. Tony WORLD CITIZEN SM #266

Fuel Pre-Filter System & Tank Questions
eric freedman
Gary,
toggle quoted messageShow quoted text
There ate 3 or 4 baffles in the tank. The Racor number for the pre diesel filter is INFDW51125 the filter head is INFDH 12500 This is a 25 Micron filter 5" in diameter and 11" length. It takes a Jabsco 50 liter per minute vane pump with 1" ports. - This idea came from Ian Jenkins. My pre filter works as follows; There is a "y" valve just below the fill cap in the aft starboard cockpit locker. Straight down position goes to the tank. I only use that position for the dipstick. With the valve turned sideways the fuel drops down to the Jabsco pump mounted directly on the aft engine room bulkhead. From there it runs into the Racor filter then up to an elbow welded in the aft inspection port of the fuel tank. I also had a buzzer added to the system to remind me that the pump is running.

Hi Judy:
I kept my boat at Manuel Reef Marina from Dec 2004 to June 2004 and it has been there again since November of 2005. Jim Woods is the manager and a knowledgeable Amel guy. Not only that he is an extremely nice guy. He will even do some minor provisioning for you to get you thru the first day or two aboard if you ask. He does care taking on my boat and watches the lines etc. There can be surge conditions at times in the marina warranting good fender placement and good line adjusting. Yet there has never been anything major. I always enter and leave on a high tide (the tide is typically only about 12 to 18 inches). There is a well-marked channel going into the marina and you must use the slips on the south east side of the dock. There is plenty of depth there but inadequate water on the north west side of the dock. Also stay close to the finger docks when maneuvering. The finger docks aren't wide enough to accommodate an Amel and any other significantly sized boat side by side so you usually get a slip all to yourself and can stand the boat off well from the dock to ease the situation when there is some surge. The only problem you might have entering/leaving is through the last two sets of red- green channel markers as that is the shallowest part. It can be 6 ft 6 inches here (or slightly more shallow) at low tide. I have been stuck there once (full fuel, full water, 6 people and junk) and had to kedge off. On a high tide I have never touched bottom going in or out. It seems to be deeper (and Jim advises) to stay towards the red markers for the deepest water. The price is right here as well. It is about $650 per month without caretaking which is about half of what it is in Nanny Cay (where I couldn't get a slip even 18 months in advance). Regards, Gary
