Re: [Amel Yacht Owners] Forward bilge water


The water was not oily. The boat is a 1998 SM. Location is St.
Thomas, USVI. Since I have placed the securing pin in the
bowthruster, I've had no further water. However, I've not been out
sailing since I discovered the water. Next time I go sailing, I will
be using the bow thruster to exit and enter my dock area. After using
it, I will again secure it with the pin, and will be checking for
water in the forward bilge.
The previous owner performed the Amel recommended modification to
prevent the bowthruster from coming out of the boat, but to my
knowlege has never changed the bowthruster seals. The main engine has
about 900 hours, to give you an idea of how much its been used.

Is the water oily that is in the bilge?

What is the year of your boat?

Is it a super Maramu?

The owners' manual will not help you to change the bow thruster seals.

Maybe I can help you.

where are you located?

Subject: [Amel Yacht Owners] Forward bildge water

Hello all;
In the process of preparing to install an electric toilet in the
forward head, I checked the forward bildge next to the head where the
seawater intake thru hull is located. I found a small amount of water
(1-2 inches) in the bildge. I did some investigating on the owners
site and found the info below, Kimberit and others indicate the
likely source is the bowthruster needing seal replacement, and further
indicates this can be done in while in the water using "bowthruster
removal tools." The info I have on board about the bowthruster is
very sketchy. I have contacted Amel for a boat manual several days
ago but so far they have been unresponsive. Any further advice would
be appreciated.

The editor dropped the decimal point . my thruster takes 3/10 of a
of oil.

Where are you located?

We rebuilt the bow thruster as we were getting water and oil
coming into
the bilge due to the thruster leaking at the rear seal.
The rebuild is very straight forward if the boat is out of the
water. If
you boat is in the water you can remove it by using the bow thruster
removal tools.
The removal of the thruster is covered in the manual.
Once you have the thruster out turn it upside down to drain the oil.
Having done this remove the prop. Behind this you will find a lip seal
similar to the one on the prop shaft except smaller. Just pry it out
grease a new one and install it. It can be pushed in very easily. It
appeared Amel uses some blue silicone to hold it in on the outside
On the thruster's vertical shaft, you will find two foam seals
that are
just removed by hand. Glue two new ones in place. Where the thruster
goes through the hull there is another lip seal held in by two screws.
Just remove this and install a new one. On top of this seal was
spongy disk seal, which we also glued down. Then just fill the
with point 3 (3 liters) of 90 weight oil.
I believe thrusters vary from boat to boat as Bel Ami, which was
next to
me, took ¾ liter of oil, and has a different mounting arrangement. My
owner's manual has a good drawing of the cross section of the bow

Will you be in the virgins mid February?

Hi Eric:
I saw your boat at Marina Cay in Road Town a couple of weeks ago.
Looked bristol. Could you please describe in detail the bow
thruster seal service process? What do you need to check on the
rudder screws? Do you just need to check that they are tight?
Thanks, Gary Silver Liahona Hull # 335 Sea Cow Bay, Tortola

We just had our bottom done. It was sanded and we had 2 coats of
ultima ablative paint applied. We used 5 gallons.
I also replaced the two lip seals for the bow thruster- one on the
thruster shaft and one in the thruster through hull opening and 3
inserts. You should also replace the wearing out bearing and the 3
on the prop shaft and the sail drive oil. The zincs on the rudder
the zinc and bearings on the weed cutter if you have one. Also,
the screws in the rudder hinge.
