Re: Bow thruster tube anomaly

If it is available to you a product called PB Blaster I believe is the strongest product to remove rusted assemblies.

I always drop the bow thruster a few inches every season and coat the motor spline, the bearing at the top of the spline and then use my pinky and then a q tip to fill the bow thruster receptacle. I use marine trailer wheel bearing grease for this.

 

I am not on Kimberlite today , however I was wondering if it is possible to use the long nozzle on the PB blaster can and enter the motor through the cooling slots in the side. Then pointing the nozzle as far down as possible load up the bottom of the motor with a bunch of PB Blaster. Hopefully it will go through the lower bearing and enter into the motor spline.

 

On another important subject.

Just as another preventative measure I remove the pin from the main outhaul twice annually and coat it with Never Seize. It comes out easily every time. It is not a bad idea to also remove a few thousands of an inch from the key on the outhaul shaft.

Hi Guys,

 

I have the oldest SM. HULL 007!

 

I had lots of difficulty removing the foot in 2015. I used lots of WD40 and repeated use of a heat gun. It came loose eventually and is now a cinch to detach as I coat the shaft with high temp silicone grease upon reassembly.  

 

PATIENCE, LOADS OF WD40 AND HEAT. 

 

Good luck

Re: Bow thruster tube anomaly

 

Even though it was Amel about 12 years ago that told me about the "drop method," I do not recommend it, and, in fairness, it was before they developed the tool. 

Maybe you can fold 200 grit wet/dry sandpaper several times where the grit is outside on both sides and insert it around the tube, increasing the friction between the tool and the tube.

What is the tube composition? How would you repair gouges in it?

So those 8 screws do nothing to hold the thruster shaft in place?

Hey all, I did buy the tool. It didn't work, kept sliding incrementally down the tube no matter how tight I tightened it... Can I put something under the metal to improve the grip??

Davi,

Don t do the lift and drop, I did it some years ago and damaged the polyester cage.
Use the amel tool or similar to extract it.

Re: Bow thruster tube anomaly

Hi All,
I had similar problem. Rust over the motor is creating that problem.
There is a special extractor tool sold by amel which is holding gently on the tube and extracting by moving screws pushing on the motor.
I am removing the tube every year and put a fair amount of grease on the motor connection to the tube.

Re: Bow thruster tube anomaly

 

Davi,

I know that this is hard to believe, but I can remember at least 6 owners who experienced the same thing. I told them the most important thing you can do is be patient. In all of those cases, with all of the things you are doing, they were eventually successful without damaging the bow thruster. In my opinion, this will never happen if the bow thruster is serviced every 2 years and the bow thruster is not in use, it is locked up with the locking pin inserted. 

Were you able to apply a little twisting motion? In the hardest case, it was a very slight twisting motion (back and forth) and some vibration added to the cast iron base of the motor.

The reason the tube is stuck is saltwater entered the joint between the motor base and the tube. Rust on the cast iron base was the result of the saltwater and the rust filled the close fit between the tube and the cast iron motor base causing a very tight fit. The tube and the motor base are not rusted together because the tube is not metal. I understand that the tube is now very tight in the motor base.

Your bow thruster may be irreplaceable. I am not sure, but if not, one day soon that will be the case. It is important to take care of it like everything else I know that you do on your Amel.

I suggest that you walk away from this for a day or two.

Best,

Bill

Regarding spike back protection, I think it best to explain why.....  Everyone should understand the protection parameters of their battery's BMS.  The BMS is there to protect your batteries, from High Voltage, Low Voltage, Over Current, Low Temperature, and High Temperature.  The BMS protections vary greatly between brands , but that should do it for most.  So, lets say your Alternator is charging at 28.4V,  that's great if the BMS's High Voltage shut of is at 29.2V.  But, what if you have a spike in the alternator's charging voltage (above 29.2V), or some type of failure in the battery's BMS...... your BMS will turn the battery off, and then your Alternator is instantaneously looking into an open circuit.  AND, You just smoked your Alternator.  

https://www.youtube.com/watch?v=03SQMDnY6O0

This device should help anytime BMS shuts down your batteries, including your Victron Charger would feel less stress when the BMS does it's job.

In theory the $99 device Bill mentioned should save the alternator in this scenario.  I didn't think about this, but this device makes a lot of sense.  

Thanks Bill!

Sometimes, I forget to start with a simple solution. 

How many Allen bolts did you remove from the base of the motor? It should have been 4.

Davi, 
the small screws are to keep in place an internal metal ring that is where the 4 allen screws are screwed. Did you remove all 4 alle , some year ago I forgot one and I try to pull hard with no results, of course. 
I rem6in a previous post that someone build a tool to extract the bowthruster leg from the motor 
Good luck

Re: Secondary Saltwater Manifold SMs & 54s, and possibly some Santorins, Mangos, and Maramus

 

A US Amel 54 owner has ordered and will install the PVC Secondary Saltwater Manifold. The 54 Secondary Saltwater Manifold is much more complicated than the SM2k. The SM2k Secondary Saltwater Manifold prototype is completed and ready to order. I negotiated a 15% discount for all Amel owners from SOTOMARIN, France. They are the supplier to Amel for the PVC manifolds beginning with the 55 and including the 50 & 60. 

The Amel 54 Secondary Saltwater Manifold kit is 457.18 ‎€ less15% Discount of 68.58 ‎€ = 388.60 ‎€ (Net XVAT + shipping)
Unless you need it immediately, I suggest we wait until I have a report from the first installation.
The Amel Super Maramu 2000 Secondary Saltwater Manifold kit is 437.36 ‎€ less 15% Discount of 65.60 ‎€ = 371.76 ‎€ (Net XVAT + shipping)
This is a simple installation and very straight forward. It is ready to order...see below
