Hi just as a oh by the way. BE VERY SURE you put a hose clamp around the tube before working on the unit so it does not drop out of the hull.

Hi Gianni,

Yes, remove the 4 studs and then the 2 circlips.

I did not require an extractor to remove the bearing.

Pleased that motor is not damaged-- cost is 2000 Euros.

Re: [Amel] Bow thruster

Malcolm Phillips <MPhillips@...>
 

Hi Gianni,





The bearing at the bottom of the motor has failed due to the
boat having been sailed sometime

with the bowthruster down. The danger is that the rotor on
the electric motor is damaged and the

commutator requires to be machined. In any event, the bearing
is readily available and is retained

in the cast iron housing at the bottom of the electric
motor.



The best method is to disconnect and drop the bowthruster
assembly and then lower the electric

motor onto blocks inside the enclosure without disconnecting
the power cables. The end housing

can then be removed and the bearing replaced.

I have replaced the unit on a friend's S/M and would urge
some caution as the electric motor is

VERY HEAVY.!

The replacement electric motor from Amel is VERY expensive and
it is well worth contacting a local

DC rewinding electrician to skim the commutator and save the
unit.



All the Best 1

Gary, I should have added that the led light was not illuminated.While
operating the windlass the gauge read 00 . A meter read just 3.2V across the
terminals, I assume it should be 24V, is that correct? The source for the
power, where is it originating from? I need to work backwards to the source to
see where the voltage drops.

Thanks,Pat SM 123.

Super Maramu for sale

asm283 <no_reply@...>
 

Reluctantly We are putting our 2000 Super Maramu for sale.

She has been cruised for only 4 years since new and is in great shape.

She is located in Aukland New Zealand. This may sound far to someone in the US or the EU. I invite you to look at a map. 1,200 miles from my slip you have arguably the greatest cruising grounds in the world. Tonga, Fiji, Vanuatu, New Caledonia, The great barrier reef Australia. French polynisia is a more robust 2200 mile sail but quite doable. Not to mention New Zealand itself as a truly magnificent destination. The boat has been imported into New Zealand wich means that she will be tax free and can remain here indefinatly. She is reasonably priced, well equiped and in great shape.

For further information vito.ciaravino@galaxyprint.com

Thank you

Re: chain counter

Do you have an LED indicator light illuminated on the sensor? If not you don't have power to the sensor or you have a faulty or miswired sensor.

When you say the gauge registers 00 is that while activating the windlass? If you have an LED indication and the sensor is properly spaced to the magnetic knub on the windlass drum, then you should get an indication.

How about some more specifics.

Re: [Amel] Re: bow thruster service

Ian Shepherd
 

Jluc,

you are right. It's design is far from satisfactory. The bow thruster on
my first SM shed propellers 6 times in 27 months, and due to an
oversight in design, it actually sank my boat when the tube failed and
the whole unit fell out of the boat. On my second SM, the nylon screws
have been made thicker, and happily I have not lost a single prop in 7
years. The anti torque modification has cured the tube failure problem,
together with the whole unit now being enclosed in a water tight
compartment. However, the water ingress and corrosion continued to be a
serious problem and I decided to make the whole unit better as follows:

I had a thin stainless sleeve manufactured so that the lip seal could
run on a proper surface and not on the somewhat rough texture of the
shaft itself. I since heard that you can buy stainless sleeves off the
shelf that will shrink onto the shaft. Check this site for posts on this.

I use seals that are fitted with a stainless spring. They last longer.

I replaced all of the open ball race bearings with sealed bearings. This
does mean that you can no longer pour oil in from the top if you use a
sealed bearing on the vertical drive shaft. To overcome this I removed
the back plate of the bow thruster and packed the whole unit with water
proof grease. I also filled the area between the outer shaft bearing and
the lip seal with some grease, but not too much else you will not be
able to tap the seal fully into its housing. Grease will not disappear
like 90 SAE oil.

It's been that way now for over a year now with some 4000 miles sailed
in that time, and has run perfectly. It also runs more smoothly. I have
not yet removed it and taken it apart to see whether any water has got
in as there has been no noticeable change in the noise which is a good
clue that the gears are running in sea water and not lubricant.

When I looked over an Amel 54 shortly after it first appeared, I noticed
that it was fitted with a bought in thruster made by Schleiper. Maybe
Amel have finally admitted that their home made unit did not meet their
usually high standards.

Hi Pat have you ck'd the tightness of the terminals at the wire ends

Ck the distance from the sensor to the knob on the drum it should be less then 10 mm 3/8"

Is the winch switch on

I installed a new sensor, I discarded the brown wire and connected the blue and black wires as per instructions . I still only register 00 on the gauge. I checked the voltage at the sensor and found only 3.2 volts. Does anyone have a thought on what may be my problem ?
Thanks, Pat SM 123

Gianni:

As per our several discussions via private email, the bearing in the
base of the motor that supports the spline shaft is an NSK 6204VV
bearing. Evidently the 6204 bearing size is very common and the VV
means that the bearing is sealed with a rubber seal on each side. The
bearing is a Single Row Radial Bearing; 20 mm ID x 47 mm OD x 14 mm
Wide; Double Sealed, Non-Contact; C3 Clearance.

I was able to purchase a couple on ebay at the following link:

http://cgi.ebay.com/ebaymotors/New-NSK-C-Series-Bearing-Part-Number-6204VV-/290540406001#ht_500wt_1107

Price is $6.99 US each and the seller will ship internationally.

Extraction of the bearing and replacement is another issue. When you
have accomplished the task please write it up and post it in the Files
Section of the forum for the rest of us. Also, you could upload your
photos to the Bow Thruster Service File in the Photos Section. I think
they would useful to encourage everyone to annually service this area
and take care of corrosion control.

Best of luck,

Gary
