I got from Amel 5 parts to replace the seals on the bow thruster. Since I have never done this before myself I am not sure how to position those parts. My assumption is: 1. Two of the foam rubber rings be placed outside the hull on the shaft of the bow thruster. 2. One of the foam rubber rings to be placed inside the hull on the shaft. 3. The large rubber gasket (ring) to be placed where the shaft penetrates the hull - but wich side upside??? 4. And there is a small rubber gasket (ring)and I have no clue were to put it? If there is anyone who knows how to do it I would be very thankful for the relevant information. Rainer Bichlbauer
