Re: Speed vs. RPM

Hello Tony
This is not an uncommon accurence on the Volvo 80hp. What you need done is to have the turbo charger removed and have the carbon inside the turbo removed. This is not a big deal so dont let your mechanic make it one. What happens is that carbon deposits built up inside the turbo housing and stop the turbo from rotating. Thus the reduction in power. Once this is done and all things being clean you should be able to run at 2700 to 2800 RPM and have a speed of about 8.5 knots. Hope this helps Vito WANDERER ASM#283 --- In amelyachtowners@yahoogroups.com, "agav8ter" <agav8ter@...> wrote: the Volvo engine that has a sticker on it saying built by Perkins, wewere told it is 80hp.

Speed vs. RPM
Ag Av8ter
Hello all,
We have a S/M #266 and it is fairly new to us. Question: #266 has the Volvo engine that has a sticker on it saying built by Perkins, we were told it is 80hp. We also have the Amel autoprop. The prop itself is clean and the roller bearings that are visable are clean. The blades rotate easily. When in calm water she will run at about 7.5 kts wide open, but she will only turn up 2,200 RPM. The Volvo manual says it should turn up over 4000 RPM. In rough water and head winds, at 2,200 RPM we are lucky to get 3 to 4 kts. Is this a typical situation for a SM? Sure seems overpitched. Does not make much smoke and runs at 90C. Ideas? Thanks for your help. Tony

In the Perkins at least, the heat exchanger has its own zinc which should be changed each year as a service item. Low down at the aft end of the exchanger and quite accessible is a normal looking bolt which, if you unscrew it will look just a like a flat plug, because the zinc, a tube shape of a few centimetres length, will have worn away. Take the plug to a good chandlery and you should find a replacement easily. I believe there is also an exchangeable zinc plug for the water heater but not on my boat. Regards, Roger, Zorba, Mango 28

Dennis if you are having problems with your heat exchanger, the remedy will probably have nothing to do with the rest of your bonding system. The connection of the heat exchanger to your external zinc, or the conductivity of the water lines coming in and out of the exchanger, are not the issue or the problem. The heat exchanger needs its own protection separate from the rest of the metal fittings on your boat. The metal in the exchanger, and the water around it, create their own problem. A battery of sorts. The exchanger needs its own internal zinc plug. Connecting the heat exchanger and or the engine to the bonding system does nothing. Roger has given a good recap of the various theories and applications. I believe that it is better to connect everything together. More is better. The whole idea behind the connection of all the metal parts is to equalize the conductivity between each of them, and then attach the same bonding cable to the zinc which is lower on the galvanic scale so
it corrodes. Only those parts which are exposed to the same body of water are protected by the zinc which they are connected to. That is why your exchanger needs a separate system. So would your water pump, transmission cooler, etc, but you can only do so much. Connecting everything only works if there is no stray current coming from other sources. Maybe there was a problem with stray 12 volt current coming from your engine, which was causing a problem, so a previous owner severed the bonding ground to eliminate it rather than addressing the problem that was causing it. The same is true with the dockside power. Another boats electrical problems can be transferred to your boat through the ground wire in the power cord, causing your boat to become its zinc. A power cord that has dipped into the water for a period of time can get saturated with water inside and current will cross over from the hot wire to the ground. You can also get a salt bridge just inside the plug on the dock cord from exposure to the air alone. I personally studied bonding systems intensively and although I learned a lot of theories, it is clear that the application is part science, part myth, and part luck. I think every boat has its own issues, and needs a system tailored to it. Some boats have no problem connecting the bonding system to the ac ground, some do. I think you just have to take in a much info as you can, make your own choices, and then monitor it as best you can.

Re: Mango Grounding
Roger Banks <roger.banks@...>
Hi Michael
toggle quoted messageShow quoted text
Nice to hear from a Mango owner; there don't seem to be too many of us participating in the forum. I wouldn't describe myself as an expert, but am happy to help you with some suggestions. The zincs rapid disappearance definitely indicates something is wrong. After 18 months my rudder anodes were slightly used, and of course I changed them anyway. I was puzzled about why the only anodes are those on the rudder and was worried how I could place a suitable anode to protect the propshaft and engine. Investigation revealed that the rudder anodes are connected to the grounding strap which can be seen emerging by the rudder post (under the aft bunk), passing along the locker under the aft bunk, then appearing again in the engine room close to the prop shaft, tacked along the bilges under the engine, across to the engine earthing point, and so on through the boat. Thus no other zincs should be required. I've tested this with a multimeter and can report there was no resistance between the rudder anodes and the grounding strap sampled at several places through the boat. Your situation indicates that there is regular electrical activity through your anodes into the sea water; perhaps also your anti- fouling is copper-based (as is common), which might be producing the paint blistering you describe. It's important to recall that the DC grounding system to the anodes is intended to connect your anodes together for protection from galvanic corrosion, i.e. it is not necessary or desirable in the context of your DC battery circuits, particularly the services side. With regard to the services side, unlike a car, where a single wire leads to, say, a lamp and the return wire is grounded to the car body, on a boat all DC circuits should return via a negative cable to the battery (bearing in mind that many services cables lead back to the common earthing point in the electrical cupboard above the galley, and thence by a heavy-duty cable to the service batteries). The engine, being an automotive component, does have a number of electrical contacts, mainly sensors, which run to earth via the engine casting; however these circuits are completely separate from the services-side circuits and, when the engine batteries are isolated, are inert. In operation there should be no reason for earth leakage unless there is a resistance or break in the route back to earth, so perhaps you should check your main fuse (mounted on a tray at the aft end of the engine) and all connections on the route from there back via the starter-motor to the batteries (on my boat it's to a services battery negative post and thus via heavy-duty cable to the engine batteries); check all the connections around the starter-motor especially as inability of the commutator cranking current to return to battery negative would result, presumably, in a heavy discharge via the grounding strap into the sea (consistent with your description); similarly if the services- side to engine battery negative connection is not good. (Did you do your protection check also while the engine was running?) If in doubt, clean or replace all these cables until your problem disappears. The services and engine battery banks should have completely separate electrical wiring systems except for the one heavy-duty cable direct between the battery bank negatives. There should be one position only at which the DC system interconnects with the grounding strap, which is at the engine earthing point; on my Perkins 4.236 this is forward on the port side of the engine. Thus, when the engine batteries have been isolated, which is presumably most of the time, there is no cause for electricity to be circulating via the engine into the grounding strap and so on to the rudder anodes. You may want to check your wiring carefully to see if any other DC/ grounding interconnects have been made; check that each grounding system (DC, AC, HF, lightning) is separate from the others, subject to sensible interconnects, e.g. if the HF counterpoise is grounded to the engine or the grounding system, there needs to be a gap of one tenth of an inch (by fastening to a piece of phrenolic or electrical circuit board), bridged by suitable capacitors (which are transparent to HF but block DC); consider cutting the grounding strap from the aft head intake and from any other "passive" thru-hulls below the water line (I'm afraid I'm not familiar with a MaxProp). I addressed this sort of thing in my previous posting. They're great boats but in all these years many pairs of hands have been doing stuff. I'm amazed at what I find even professionals have done wrong. For instance, only recently in hunting down the cause of excess gassing in the service batteries, I found the regulator on some new solar panels I had installed last year is undersized; and just last week I found through detailed enquiry on the manufacturer's website that the regulator on my wind generator is under-sized too. I do everything myself now! Have fun and don't forget to report back if you have a success. Regards, Roger, Zorba, Mango 28

Dennis, I am doing the same thing, and trying to figure out what was intended to be bonded to what in my maramu as well. I didn't know that there was a bonding ground attached to the rudder until I read a response to your question. I have been having my dive service install the zincs, but I thought they were a stand alone system. Now I really have to look. I will watch the reply's to your question, and supply my own info when I figure it out. Eric Maramu 105

Re: [Amel Yacht Owners] AMEL MARAMU GROUNDING SYSTEM
Roger Banks <roger.banks@...>
Hi Dennis

Yes, I've spent quite a bit of time looking at the grounding systems and there a few good articles in magazines and on the internet, but some how they never quite get down to specifics of every situation. There are four grounds which need to be kept separate, subject to certain approved interactions: AC, DC, HF, and lightning. Regarding the DC ground, which is the subject of your enquiry, the logic not many years ago was to connect together every metal thru-hull, which Amel have done elegantly with the grounding bus you describe, which connects to the zinc anodes mounted either side of the rudder (at least it's so on my Mango); this system still holds good if you spend your whole time in remote anchorages, but entering a modern marina exposes your boat to stray electrical currents from and between other boats (DC) and pontoon services (AC). This can set up a galvanic corrosion reaction, in which the current enters by one thru-hull and exits by another, taking with it some metal. This is also a problem where two or more metals are in contact in an electrolyte, e.g. sea water. Therefore the common wisdom has altered since your boat was built to say that thru-hulls should not be linked together. Bronze thru-hulls, such as for toilet water intakes below the water line, are considered stable and may happily be left alone, i.e. not connected via a strap to any other thru-hull which would expose it to the corrosion effects described above. There are some situations where connection is unavoidable, such as stainless steel (itself an alloy) prop shaft mounted in bronze tube and with copper propellor. It's essential to ensure the grounding bus is connected to both the prop shaft and its mounting tube which, as I recall, is visible inside the engine room, between the engine and stern gland. If you look further you will find that the engine water intake cock is connected by water to the raw water manifold and to the engine itself and, if I observe it correctly, to the diesel supply system via that fluid and to the fresh water heater. Some of the bus gets pretty inaccessible in these places. I'm not 100% sure of the electrical connectivity via fluids of some of these items and would be glad of contributions by others. It seems to me that whether the engine etc should be connected to the grounding strap, and thus the zinc anodes, is a question if there is more than one connection to the sea water, i.e. via the raw water intake and what else? I believe the prop shaft is isolated from the engine by a flexible coupling. The exhaust water exits above the water line (as do all basins and toilet water exit points), so does not count. Thus if the only connection point between the engine and sea water is the raw water inlet, it may be correct that the ground strap was severed. If your model of Maramu has a ground strap connection to a keel bolt, unlike my Mango where the rudder anodes are the single point of protection, then you may need to restore the connection and make sure the keel bolt is protected by an anode, but it may be your analysis of this is not correct.

Hi,
For those of you who haven't been to www.yachtfiona.com <http://www.yachtfiona.com/> I would strongly recommend it. He is a CCA Blue water medal recipient and has circumnavigated Fiona 3 times. My friend Eric Forsyth has over 200,000 miles on his home built boat and at the age of 74 is heading out again for another circumnavigation. ( he is extremely fit) For those of you who are looking for a ride of a lifetime drop him a note. Many legs need crew. He will be leaving New York in May and headed for the Antarctic with stops along the way for crew changes. Then up the west coast of Chile to Panama and home.

Puerto Williams
eric freedman
I just came across this for everyone's info.
Fair Winds, Eric Amel Super Maramu #376 Kimberlite Puerto Williams : Profile Clearance Yachts entering the Beagle Channel area should contact the Chilean Navy on VHF Channel 16. Puerto Williams is a naval base, but yachts are welcomed there. Cruising boats are usually told to proceed directly into the small western basin, close to the airport, where there is a concrete dock. Shallow-drafted boats may come on its inside, or tie up alongside the Micalvi, a former supply ship, now used as a yacht club by the locals. Officials will visit the boat here, after which the captain must go to the port captain's office to complete formalities. It is essential that those for whom this is the first port of entry into Chile insist on being given the compulsory customs certificate. Those who leave without it will have serious problems when clearing out of Chile. From September 2004, all the foreign yachts entering Pto. Williams had to pay a new tax. From Monday to Friday between 08:00 and 18:00 o'clock, and Saturday from 06:00 to 13:00 the Authorities charged US$ 40 every time a yacht entered or left this port coming from or going to a foreign country. In overtime, they charged US$60. At the end of October this tax was reduced. The fees which now apply are as follows: Yacht up to 25 tons: each time a yacht enters or leaves the country it must pay: US$2.60 (Monday to Friday 0700 - 1900 and Saturday 0700 - 1300). Outside of these hours, the charge will be 50% more i.e. US$3.90 (weekdays 1900 - 0700 AM and from Saturday 1300 to Monday 0700). Yacht from 25 to 1000 tons: each time a yacht enters or leaves a port or a marina it must pay US$40. In overtime 50% more (60 US$). Please note: A yacht less than 25 tons of TRG must pay this tax only when it enters or leaves the country. A yacht more than 25 tons of TRG must pay each time it enters or leaves a port of Chile, even when it sails in Chilean waters without leaving the country. Lighthouse and beacon fees are : US $ 2.88 per year or US$ 0.88 per TRG for all the trip. Capitania de Puerto Tel:+56 61 621090, Fax:+56 61 621090, VHF Channel 16 cpwilliams@directemar.cl Docking Puerto Williams, Chile's most southern city, is the usual jumping off point for Antarctica. It is situated on Navarino Island in the Beagle Channel. The most pleasant, and safest, berths are at the Club Naval de Yates Micalvi. It is based in a small inlet at the western end of the harbour. There is an anchorage in Seno Lauta, with good holding, but exposed to both easterly and westerly winds. It is free, but requires permission from the Port Captain. Yacht Clubs Club Naval de Yates Micalvi Puerto Williams, Chile There is 3.5 meters on the outside of the'Micalvi', and 2 or less alongside the portside. Water, electricity and hot showers are available. The bridge and forward sections of the ship have been turned into a very popular bar, for both passing crews and locals alike. There is a warm welcome here for everyone.
