Access to mizzen topping lift bungee 1988 Maramu

Graham Cresswell <grahamjcresswell@...>
 

Does anyone have a diagram to help me get access to my Maramu's mizzen topping lift bungee. It's gone very slack and the boom now strikes the stern crane unless it's sheeted right in. It looks like you have to get inside the boom to do anything but as far as I can see the only access would be by removing the mizzen outhaul track. Is that what you have to do?

Poor saltwater flow to engine and Onan

Bill & Judy Rouse <yahoogroups@...>
 

Jeff,

Terrible Internet here. No local phone. So, I am replying by email and copying the Group. I am sure there are others who need to know.

Marine growth through the sea chest and into distribution lines is always a problem with flowing water and mussels and other stuff love flowing water. Your 54 always has flowing water because of refrigeration. So, you are going to deal with this more often than a SM owner. You need several "special tools" (designed my yours truly) and a wet vac, electric drill, and heat gun is very helpful.

Go to the Amel Owners Yahoo Group. Click on Photos. In the search box enter sea chest. You will find lots of info. Review all that you find.

Probable causes of poor water flow:
The line below the sea chest strainer is clogged with growth or plastic. There is a "tool" pictured in the search results above that you need to have. It is a broom handle with a bottle brush at the end. You need it as long as possible while still fitting between the inside bottom of the sea chest and the engine room ceiling. The dimensions in the photo are for a SM. Get one made. In the mean time, a piece of broom handle will work as good as a diver...PROCEDURE:
- Turn off valve
- Open sea chest and momentarily turn on AC to pump the level down, or use your wet vac to remove all of the water (best). Put the tool into the top of the valve. Open valve and press down at least 12 inches and up and down several times. Pull the tool out and quickly close the valve before water over flows. It is really good if you have a wet vac to duck all of the water out and clean the sea chest.

Next thing to check is the hoses going from the sea chest to:
- Engine and in-line Transmission heat exchanger
- Generator
- And salt water distribution manifold

PROCEDURE:
Remove the hose clamps where they join the sea chest. Take them off because you do not want to drop them. Using a heat gun, or hair dryer, heat the hoses in order to pull them off. Look inside. At one time, BeBe's (387) were crammed with mussels. I used a piece of rigging wire which was crimped and splayed at the business end and connected to an electric drill as a sort of roto-router. I have used this wire on head hoses and other things at least a dozen times. Get yourself one or something similar. Make it 50% longer than the one pictured.

Don't forget to open the boot on the transmission oil cooler...the one on the sea chest side...and using a wet vac, suck out any debris. I know that you know about this.

Let me know if this works for you.

Regarding wind, you will probably be disappointed. If you can figure out how to add 400+ watts of solar, you will be happy.

Good morning Bill:

Any chance of a Skype call this morning?  I have two questions to ask you.

1.  We are in waters with a fair amount of marine growth.  Even though I have cleaned the raw water filter, there is insufficient flow to engine and genset for simultaneous operation.  Genset impeller is good. One or the other unit runs, but not both.  Sea chest has been cleaned above valve. Diver coming Monday to clean hull opening.  Any further remedy suggested?

2.  We are considering wind generator on mizzen.  Have examined solar but not comfortable with mounting options in absence of arch. Are you aware of any AMELS using wind generator?

If not convenient to chat, please drop a note when you can.

Many thanks

Jeff


Re: [Amel Yacht Owners] 3 Phase Dive Compressor

hanspeter baettig
 

Hi Mawgan
This is not a easy thing. Because a dive compressor is something you should trust. And a workaround is in my opinon not the right way.
From a technical point of view you have 2 options which are suboptimal.
1. As a workaround you can help you with the so named " Steinmetz- Configuration"
  Useing a condensator 140 F, 400 Volt . I can send you or you googel it for the wirering diagramm.
  Using 1 phase and the neutral. 
  Problem with this low cost solution its only for 3 phase motors less the 3 kw. The Bauer Junior has after the starting mode about 2.5 kw. Also you have 50% less of tork. You have to check out with the connect compressor if its enough. Advantage is the low cost of this solution ; ca. 50€
2. Go to a specialist and buy a electronic frequency converter eg. Hitachi for about 600€
For 2.5 kw. As I assume you are not an electrical specialist as me, you may ask for professional support to install this box , wight about 10 kg ( 300*200*50 mm)
Depending what you paid for this second hand product you shall  buy a new singel phase compressor. To rebuild the Bauer Junior with a factory new 220 motor is quite expensive. I'm also interesting what Bauer in Hongkong will offer you. As an option to Bauer Junior which is a first class product there is the Coltri Compressor from Italy. Less wight, lower price then Bauer. In the diver community you will see both products.
Please feel free to ask me for more support. I will send you then my email .

Hi all,

I've just bought a second hand Bauer Junior 2 dive compressor but the catch is it has a three phase 2.2kw electric motor. I'm still waiting on Bauer for an answer but has anybody installed a 3 phase unit on their boats. Will it work or should I change the motor or try getting a digital inverter converter (expensive). The port side cockpit locker and 220v CB looks designed for it.

Thoughts please.

Just put a photo up to give you a better idea what I was talking about. Note it is not in use as I took it off the boat.

I currently have a Bauer junior running a single phase motor, the option at purchase was single or three phase. In an Amel 55 I mounted in the stern locker along side a tank rack.

When I bought Popeye it had no compressor but one had been on previously and running from a 4 kvA gen set. From some spares left I think it was a Bauer Junior. It appeared that the set up had been to run a 3 phase compressor motor from the single phase generator as the compressor had previously been in the sail locker opposite the forward heads and there was a remaining electrical box with fairly large condensers which I believe was used to convert to 3 phase. The reason for it would probably have been to be able to run an electric motor off a generator that was too small for a similar sized single phase motor. An electrician should be able to make a similar set up.

If you do not have a transformer as Kent described, and if you have the original Dolphin battery charger, and if you wire the shore power connection correctly for 220VAC 60htz, your original Dolphin battery charger will work fine.

You will need 220VAC 60htz service and an American 220VAC connector...AND, MOST IMPORTANTLY wire it correctly. Several years ago I posted photos in the photo section of how to wire the connector.

Re: [Amel Yacht Owners] Re: SM Bow thruster propellers & 70 MM key for the rudder shaft nut

Bill & Judy Rouse <yahoogroups@...>
 

Vladamir,

You should do what you want to do.You are certainly free to do that. I assume freedom is important to you...it is to me.

I happen to be the self-proclaimed and self-appointed advocate of Amel boats and Amel designs and I firmly believe in keeping the Amel designs pure.

My qualifications are much simpler than yours. In the last 10 years I have been right in my opinions regarding Amels, Amel owner issues & problems, and I have helped hundreds of Amel owners out of jams that they got into because they listened to some expert with plenty of qualifications. My reward for all of this is that I have met some wonderful Amel owners and I am proud to call many of them my friend. So when someone suggests changing an Amel design I believe it is my duty to be an advocate of Amel, presenting the "other side" of the recommendation to change an Amel design. Will I be right 100% of the time? No! Nobody is right 100% of the time and we all have plenty to learn. But, I have been right most of the time.

I will always be an advocate of Amel...that will never change!

I apologize if my posts irritated you, but I suspect that it will not be the last time, so here is another apology for the future.

With all that respect, please don't push so hard  for "superiority of Amel parts". Aluminum prop for a boat thruster should be a better choice.

Perhaps cost consideration has influenced original decision on prop material selection.

Hi Gang,
Bill’s point is taken.  I will
check to have a Delrin center hub made.  I do not  think
corrosion would be a problem with the isolation capacity of
the hub and the plastic screws.
Will check it out …

Hello Gang,
1. A member here has found BT

Same attachment as original but
for the material... you keep the safety of the plastic bolts
in the event of contact with unknown substance.
2. I have a SS specialist make
me a 70 MM key to tighten the packing nut on the rudder

If interested in either
component, post to my email address and I will try to get a

Re: [Amel Yacht Owners] SM Bow thruster propellers & 70 MM key for the rudder shaft nut

JP,

Aluminum oxidizes with salt. The prop will be in saltwater even when retracted.

On my safe the lock beeped and lights blinked many times before I replased the batteries. It was a warning that batteries are low. I ignored the warnings because I have a key.

Re: [Amel Yacht Owners] Double loss of Bow Thruster propeller...

Alexandre Uster von Baar
 

Hello Bill,

I am pretty sure the 3 “white” propeller and the hubs are non Amel.

Little precision: I have one my boat for 3.5 years with the same prop and hub (which I believe both original - I repainted the propeller with blue antifouling)
This is the first time I have a propeller failure (in 3.5 year). I think the hub was getting old, but I am open to other suggestion.

After I lost the propeller, I put back the same hub and a different propeller (the black one) which I think is genuine.

I tried to detail with pictures on: http://nikimat.com/bow_thruster_lost_propeller.html

Alex,



I strongly suspect non-Amel hubs and can clearly see
non-Amel propellers.

It is dangerous to deal with non-Amel parts.



Do you know the origin of the hubs? I remember you had a
ample supply of

these hubs when you first bought your boat. Were they on the
boat when you

bought it? Where did the previous owner get them.



A few years ago, an Amel owner of Super Maramu "Bali
Hai" told me that he

had some hubs made at a machine shop in Malta from Nylon. He
said it looked

identical to the Amel hub but that they fell apart with very
little use.

The fact that the hole in the hub elongated from very little
use, tells me

what you have is non-Amel and probably Nylon rather than
Delrin which is

much more expensive.



The black prop looks like an Amel prop. See photo I ccd you
only.



Your problems are a perfect example of what can happen when
someone tries

to use non-Amel parts such as aluminum props and Nylon
rather than Delrin

hubs.



JP Germain, listen to what I am saying. And everyone else
who wants to

outsmart Henri Amel. You are not smart enough.



There! If I haven't yet pissed everyone off, this email
probably will do

it.



Bill
