Re: [Amel Yacht Owners] Autoprop Plastic Cap and Zinc Anode Sources
william_maffei@...
If I remember correctly, Amel is the only source for the plastic H6 prop caps. I am not even sure they are available anymore. I buy the zinc (H6) anodes from boatzincs.com http://www.boatzincs.com/autoprop_specs_H6.html
They work great but they really never need replacing if your Amel is wired properly. I have never in 2 years had to change this anode. The only anodes that do anything are on the rudder. Cheers, Bill Maffei SM #195 It's all Good

James, I know SM #418. She was previously "Lady H." When I looked at Lady H, she had all sorts of "mystery wiring" and in a lot of places. I have to hand it to you if you cleaned all of that up and got it back to being an Amel. Congratulations. Best, Bill

Ron, That is because you need to "login with your Yahoo user name and password to be able to view photos and upload or download files and photos. I CC'd you of this email and I attached the photo that I downloaded for you...you should login on the website because there are lots of things available there. The dimensions for this tool are for a Super Maramu...maybe you can use this idea and make one to fit your Meltem. Best, Bill X-BeBe

Autoprop Plastic Cap and Zinc Anode Sources
Jim Anderson
Hello All,
Here are sources for both the plastic cap that Amel installed in leiu of the Autoprop zinc, and for the actual zinc-zinc for the Autoprop,including the H-6 that many SM's and 54's have. They call the plastic cap a "plastic zinc" even though it is all plastic. The source is King Propulsion in Virgina Beach, Virginia, USA tel. +1 757 962 9219 kingpropulsion dot com roderick.sampson"at"kingpropulsion"dot"com About $36.00 US plus shipping for the H-6 Autoprop plastic cap with fasteners. King Propulsion is a USA manufacturer's representative for Bruntons Autoprop so they also have the bearing rebuild kits. I have to commend Rod there because he also sells the O.E.M. zinc-zincs, but said he couldn't come anywhere near to matching the below source on pricing, and referred me to them. For the "zinc-zinc" the source is boatzincs"dot"com sales"at"boatzincs"dot"com +1 978 842 9978 $19.53 US for the H-6 Autoprop zinc with fasteners. They bill themselves as the zinc anode online superstore and have just about every kind of zinc imaginable, at good prices. Wishing smooth sailing and endless broad reaches to all, Jim SM384 Sirena Azul Seattle

Re: [Amel Yacht Owners] I dont think it is the same engine as mine Isolated ground on a Yanmar
eric freedman
Bill, I understand what the new wiring kit does, however it was made for a different engine. I have ha 3 4JH yanmar engines and they were all identical except one did not have a turbo, one did , and my current one has the turbo and intercooler. The theory is the same and the schematic diagram might look the same but it really depends on how the actual engine was wired. Fair Winds Eric Kimberlite Amel Super Maramu #376

Eric,
Every engine will be somewhat different, but the "Amel isolation wiring theory" should be the same. The information I searched and found on the Yahoo Amel Group website was originally posted by Kent and, I believe, that it refers to a newer Yanmar than the Yanmar in Kimberlite. I do not know believe that we know the hull # of the boat that this thread is referring to.

Amel did this to eliminate galvanic corrosion. Amel has done more than any other boat manufacturer to eliminate galvanic corrosion. This is the reason that your mechanic has never seen it.

This problem started as a non-functioning tachometer. The flywheel sensor ground is indeed bad, pointing as you say up the line on the wiring loom or somewhere else on the engine. A jumper wire placed on the tach sensor ground connector to another engine ground point brought it to life. All was well until the genset was started on passage.

In my initial thought on the initial tach issue I was thinking a bad ignition switch, but since finding that the tach sensor ground wouldn’t work, it points to somewhere in the loom or on an engine connection in my mind. Opening the wiring loom on the engine would be a big job for me, if it were in the loom from the engine to the helm, that would be another matter entirely. Jumping the ground to get the tach working was too easy. Obviously, there is a larger problem. What do you think the likelihood of the ground short being in the engine wiring loom? Could it be a bad sensor or relay in the same circuit? Does a wiring diagram of this motor with the isolated ground shown exist?

Ditto on Bob’s comment. I would suggest starting at the sea-chest and working your way down the salt water flow. The tranny cooler is easy to service (do not over tighten when putting it back on or reconnecting the hoses). Also check the 90 degree elbows at the raw water pump. On the Yanmar, the raw water pump has a bar across it at the intake side. Not sue if Volvo has the same. I found a small clam lodged in there once. It took me forever to find it. I tore apart the entire cooling system and missed it the first time.
Most temperature issues are because the heat exchanger is not clean enough followed by after cooler flow issues for turbo charged engines. Taking the heat exchanger to a radiator shop is better than messing with the acid required aboard the boat.
Also check the thermostat on the coolant side. You can place it on a pan of water on the stove with a thermometer in it heat the water. Note the temperature when the thermostat operates. Check to see if it is in spec.
My guess is if you closely inspect the seawater flow passage from start to finish, you will find something partially blocked.
Also, check the manual for operating temperatures. Engines will increase in temperature as RPM or load increases. However, there is a cap on what it should warm to. The range should be in the owners manual. Our Yanmar runs at 180F under moderate load and 190F at full load.
Hope this helps. Good luck.

Bill , I agree , if all the blades are intact one assumes all is good. I had a problem on a previous boat where the plate on the pump behind the impeller wore as well as the cover plate diminishing efficiency .

When you change the impeller, closely compare the old one to the new one. I believe that you will probably find the same thing I have with wear at the ends of the blades. Once I found what appeared to be a 45° angle cut at the end of used impeller blades, with all of the thickened ends of the blades worn off. It was wear.
I am aware of the rubber separating from the metal hub with low hour impellers which are left in place for over a year. This causes the rubber to slip on the hub, reducing water flow.
I think most of us consider only missing blades as an indication of failure. Best,

Re: [Amel Yacht Owners] Re: Negative ground slave solenoid

James, there are many discussions on this site about the benefits of an isolated ground. Did you read my note to you about the black wire that all of the negative items on the engine are connected to? Please review what I wrote and then if you have any questions please ask me. I became intimate with the engine wiring after spending 5 days hanging over and around the wiring. I believe you have a bad connection shorting the black wire to the block or something else. The problem is almost 100% in the wiring of the engine and not in the harness to the control panel.
Amel does not have a wiring diagram of what they did to the engine. However do not remove the isolated ground on either engine, you will open up a big can of worms. If you are electrically competent just go after the black wire that starts at the Valeo solenoid and check every connection. You might have to use a set of channel lock pliers to remove the wiring from under the turbo. I will post other photos of the wiring to the photo section in a few minutes.

What was Amel’s thinking on the need for an isolated ground for the generator and 185 amp alternator? It seems to confound local Yanmar techs as there are no Yanmar wiring diagrams available to them. Their initial reaction is to want to take the isolated ground out somehow.
This problem started as a non-functioning tachometer. The flywheel sensor ground is indeed bad, pointing as you say up the line on the wiring loom or somewhere else on the engine. A jumper wire placed on the tach sensor ground connector to another engine ground point brought it to life. All was well until the genset was started on passage. Genset started, isolated ground started clicking rapidly, engine failed to start, isolated ground was open, top push button engaged, engine would start, but tach indicated interference.
In my initial thought on the initial tach issue I was thinking a bad ignition switch, but since finding that the tach sensor ground wouldn’t work, it points to somewhere in the loom or on an engine connection in my mind. Opening the wiring loom on the engine would be a big job for me, if it were in the loom from the engine to the helm, that would be another matter entirely. Jumping the ground to get the tach working was too easy. Obviously, there is a larger problem. What do you think the likelihood of the ground short being in the engine wiring loom? Could it be a bad sensor or relay in the same circuit? Does a wiring diagram of this motor with the isolated ground shown exist?

James, The answer to your question requires more words than I have this morning, but I can answer why... Amel did this to eliminate galvanic corrosion. Amel has done more than any other boat manufacturer to eliminate galvanic corrosion. This is the reason that your mechanic has never seen it. There is a wiring diagram on the Group website at: Believe! Where are you, what model Amel, and hull#?
