Hi Dennis,
Yep tried that. I need to do a rebuild on the alternator anyway. Did you have any issues sourcing the bearings?

Thanks James, I used your easier method last time. Might try the "fancy" method now as it did not solve the issue. Then if it continues at least I know it is not that.

-- Thanks Nick. Your description is perfect. I will have another go at the alignment. Due to location and with no assistance around at the time I did it myself with only advice from other cruisers.
It is out of the water currently so I will try your proposal of the temporary bearing while out first when I get back to the boat and then check again once I get back in the water. Will also get the prop shaft checked.
I have one other question if you could help. Due to the prop shaft generator the belt pulley sits between the vetus coupling and the transmission. I have attached some photos from another post that shows the arrangement. from memory the 4 bolts shown on the photo "vetus coupler" bolt through the coupling and the pulley holding it all in place.
When measuring the the alignment access to the back of the transmission is limited due to the generator pulley. I am not sure if there is enough length in the shaft to pull it forward without the pulley in place. Do you have any thoughts on this?
Also it is only at certain revs that the squeak was occurring. Very low revs and then between 1500-1800.

Dennis, that created a dead short of the house bank. Something melted because there is enough amperage in the house bank to weld. Look for a burned wire. Also, try to find the shunt for the battery monitor. It may have blown because on your boat it is probably rated at 12 volts 200 amps or less...a dead short would have been more than 200 amps. It will be on the negative side. I am not sure if it will look burned, but you should check for continuity between the two large posts. I am not sure, but I think if the shunt is burned, the monitor will still work because of which side of the shunt it is connected. The shunt will look something like this and will be located close to the batteries:
It will be wired something like this:
Good luck.

You need to get a meter and check the voltage at the main on off switch inside the engine compartment. If there is no voltage there there may be a fuse on the battery terminals that have blown. It is a place to start. Bill fletcher Maramu sn179 On Sun, Nov 24, 2019 at 10:26 AM sbmesasailor via Groups.Io <sbmesasailor= yahoo.com@groups.io> wrote: Electrical issues are not my strong suit.

I would suggest you do not attempt to add a grease fitting to the Racks. The steel racks take up almost all the room inside the black housing they are fitted into, and I’m not sure you can find a place to put the nipple. Even if you could, the grease is not going to circulate adequately around the racks. When I took my racks apart, they were still packed full of grease after 27 years. If you are losing a lot of grease from your racks, something is probably not right, and you should take them apart. If you are just losing very small amounts of grease, don’t worry, the racks are very full of grease.
Just my two cents worth, but having replaced my entire steering system (racks, pinion, and cables), I have a fairly good understanding of how it works.

Pat,
I haven't considered that. I assume that you are referring to the racks...the steering cable is sealed.
I assume that the "leaking grease" is coming from the rack housing at one end or the other. If I recall these ends are not perfectly sealed. And as the toothed rack moves back and forth, it could push excess grease toward the ends of the rack housing.
Keep in mind that it is the steel toothed racks inside each rack housing that will fail with excess wear and that excess wear will be very close to the center of each rack. I believe this is wear caused by the autopilot "back and forth motion." It may also be caused by securing the helm in a center position while anchored.
Amel SAV said that they are going to be sourcing these steel toothed racks and have them available, even though the original manufacturer, Ultraflex, has stopped producing them. See the worn rack below:
One rack has teeth pointed upward, the other rack teeth are pointed downward. Tooth orientation, along with primarily
center wear, should be considered when adding grease/fitting.
Translation:Corrugated Washer ---- Teflon half-rings
Possibly, the cover shown below can be drilled to inject grease. If so, this would be a fairly easy modification that could possibly add years of service to the racks.
I am worried that the metal is to thin to take a thread tap. If that is true, possibly it could be drilled, grease injected and a rubber plug inserted.
I know there are a few owners who can answer this question.
We may need a volunteer to study this further.

Re: Greasing stegring cables
Steve, I have only over the years lost no more than a 1/4 of a cup if that. Based on what you describe there seems to be adequate lubrication to spare, and as much as I am not looking for any additional projects ,I think I will then put this one on the back burner.
Thanks for the insight,

Re: Antal 120x18 Composite Fibre jib block

James,
I replaced the original Amel engine mounts on my Maramu #220 this year. The part you have circled is the bronze stern tube which will extend into the hull. It appeared that mine was bonded and glassed into the hull, it needs to be a rigid connection. The stern tube provides the attachment for the short pc. hose that the stuffing box gland attaches to, it is not supposed to be a bearing. There should be relatively even clearance between the stern tube and the shaft which allows for some engine movement without the shaft touching anywhere. As I understand things the cutlass bearing on our boats forms the aft bearing and the transmission bearing provides the front bearing to support the shaft. Nick already mentioned the two most likely causes of your squeak but I will try to elaborate a little more. Engine alignment is more than just getting the two faces of the coupling mated within a few thousandths, you also need to position shaft so that it is riding close to the center of the bronze stern tube so that it cannot touch. The fancy way to set up this alignment is to remove the stuffing box and the short pc. of hose and fit something solid like round rod of the right OD to hold rigidly hold the shaft in the very center of the stern tube, then to adjust your engine so that it is the correct height and also correctly positioned Port and Stb. Once this is done you can do your actual alignment to get the coupling faces aligned. An easier method that seems to work fine and can be done in the water is to decouple the shaft and by HAND force the shaft coupling to go as far as it will go up down and Port/Stb. You will feel solid contact as you force the coupling to it’s limits as it touches the inside of the stern tube. Note the relative displacement of the couplings to Port/Stb. and Up/Down and adjust the engine so that the displacement is the same top and bottom and side to side which will put the shaft pretty close to the center of the hole in the stern tube. Once this is done, align your coupling faces. Also I initially only did a rough alignment on my engine because I knew that the new mounts would settle a bit and they did. So after 50 hours I did a second alignment and sure enough the whole engine had settled a bit so brought it up.
As to the other possible causes of the squeak, as Nick alluded is that the shaft could be bent. You can often tell this when sailing with the engine off and the wheel turning. If the back of the engine is moving around much in time with the shaft rotation, you could have a bent shaft, if it is nice and smooth then probably not.
One final possible cause of a squeak can be from having the stuffing box too tight. With the new teflon packings you can pretty much tighten to the point where you don’t have any leakage but if you go too far the box begins to heat up, grab and squeak.
Best of luck,

HI,
The attached photo is of the stuffing box and where the shaft on my maramu exits the boat. Is the circled part another bearing that is glassed into the hull?
We have a "sqeak" or hum when the prop shaft is spinning at certain revs (both with engine and when sailing and free spinning) that we have not been able to diagnose.
The problem started following the failure of our engine mounts. The engine mounts have been replaced and the cutless bearing was replaced at next haul out, however a squeak has remained on our last short cruise before hauling out again. I have checked the engine alignment, the stuffing was replaced, but the squeak remained.
We will be back on the boat again in the new year and would like to eliminate the cause for this before going back in the water and if this is a bearing then possibly order one now.

Hi James,
1. If the boat is ashore I would check that the shaft is true. You would need to pull it and take it to a machine shop. 2. I would check the engine alignment again. It is not easy to get spot on. One of the tricks I have learned is to decouple the shaft from the transmission and centre it within the stern tube. Then align the engine to the shaft.
On some systems the shaft is floating around and can be moved a lot as there is no bearing at the engine end of the stern tube. This would be the case with a modern drip free lip seal style stern gland. From the photo I think this is what you have. If there is shaft wiggle then make up a nylon bearing that slots into the stern tube at the front end, this involves removing the shaft seal, and sliding the nylon bearing over the shaft and into the stern tube. So there is a cutlass bearing aft and another nylon temporary bearing forward. This then centres the shaft spot on within the stern tube. With the shaft centred you then align the engine to it. It needs to be spot on. Then obviously remove the temporary nylon bearing, and put back the shaft seal.
The problem is that it is much easier to do out of the water but the hull may take up a slightly different shape ashore, although if it has been carefully chocked and is nice and level a solid hull like a Maramu will probably not move much.
If in the water, I have used a greased tape or plastic wrapped around the shaft and pushed into the cutlass bearing to reduce the flow. This works quite well, but water leaking into the boat adds a bit of stress.
There are other techniques, but this is my preferred.

Re: Supermaramu wire sizes?
I guess I should have just sent you the links.😀
Thanks for the follow up Bill, I did read about Scott on Tengh rewiring with 2x50mm2 for his 5000w inverter. I believe others have installed the 3000w with the 100A wire. Can't recall the size inverter that Delos installed or if they rewired.
I did a double take on the resulting wire size from your calculations and I redid them myself and cross checked on a different calculator before I realized that the wire length should be entered in meters not feet. This results in a wire size of 50mm2 or 1AWG (actually 42.4mm2) for a 4 meter wire. That is why I wanted to confirm the wire sizes. My guestimate is that the 100Amp charger has a 50mm2 wire as it looks close to the size of another labeled 50mm wire on the boat. Then the existing 1800watt inverter looks slightly smaller, like it has a 35mm2 wire and the wire to the inverter looks even smaller, perhaps 25mm. The wire to the alternator is just a bit larger than the 100A charger, so that could be 70mm2, which would be appropriate for the 175 amp. The wire to the bow thruster (longest run and highest current @ 300-400A) looks like a 4/0AWG length of have which is between the standard sizes of 95mm2 and 120mm2.
I'm pretty comfortable with the calculations, and I am really just looking for confirmation on the existing wire sizes.

3000 watts = 13.64 amps of 220 volts: So the short answer is, assuming that the 24 volt wiring for the 100 charger watt was designed for 100 amps. You should NOT use that wire because you should expect a maximum of around 140 amps. Not good! So, replacement is going to be required. Since replacement is required, calculate the wiring size needed for the inverter/charger using an online calculator...here is one:
https://www.solar-wind.co.uk/info/dc-cable-wire-sizing-tool-low-voltage-drop-calculator I am not sure about the length of the cable run...I used 12 feet...it could be 15 feet.
The result above shows required wire is 120 mm2 = 12.4mm diameter, which is about 1/2" diameter
Hope this helps.

Hi Bill, yes I'm well aware of the different cable sizing standards. But was looking for the reference data for the actual cables in the SM.
The existing cables are well shielded and have shrink wrap covering right up to the terminal lug so the actual wire is not accessible for direct measurements.
I am just trying to understand the sizes with respect to the various loads. Several of boats have talked of replacing the original Dolphin 100A with a 3000watt Victron Multi or Quatro and I wanted to understand the impact in terms of current load and voltage drop potential.

Hello SM owners,
Does anyone know the original

1) 100 amp charger to battery switch
2) 30 amp charger to battery switch
3) Battery switch to bow thruster
The wiring does not appear to be labeled. And I'm not a good judge by eye.

Re: Greasing stegring cables
Pat,
The potential grease port location I spoke of may be easy to reach on one rack, but I am not sure about the other. See below.

I haven't considered that. I assume that you are referring to the racks...the steering cable is sealed.
I assume that the "leaking grease" is coming from the rack housing at one end or the other. If I recall these ends are not perfectly sealed. And as the toothed rack moves back and forth, it could push excess grease toward the ends of the rack housing.
Keep in mind that it is the steel toothed racks inside each rack housing that will fail with excess wear and that excess wear will be very close to the center of each rack. I believe this is wear caused by the autopilot "back and forth motion." It may also be caused by securing the helm in a center position while anchored.
Amel SAV said that they are going to be sourcing these steel toothed racks and have them available, even though the original manufacturer, Ultraflex, has stopped producing them. See the worn rack below:
One rack has teeth pointed upward, the other rack teeth are pointed downward. Tooth orientation, along with primarily center wear, should be considered when adding grease/fitting. Translation:Corrugated Washer ---- Teflon half-rings
Possibly, the cover shown below can be drilled to inject grease. If so, this would be a fairly easy modification that could possibly add years of service to the racks. I am worried that the metal is to thin to take a thread tap. If that is true, possibly it could be drilled, grease injected and a rubber plug inserted.
I know there are a few owners who can answer this question.
We may need a volunteer to study this further.
