Re: [Amel Yacht Owners] Re: bow thruster service. Problem


Alexandre Uster von Baar
 

I am a visual person myself, so try to illustrate what Bill, Gary, etc. have describe.

The problem of the 1st question doesn’t make sense to me… the shaft has the same size… going through a seal, so why should there be resistance?

Are you sure there was nothing in the water to block it?
Did you lower it straight down? not at an angle?

Unless Bill says otherwise, put lots of grease like on picture:

This will help water getting in.

Good luck, please keep us posted of what you find…

Thank you, Alexandre & Bill. Two of my three
questions are now answered: It is normal to have to trim the
2 seals on the trunk, and my prop wont come off because the
6 nylon screws secure it to a hub and one must pull the pin
out of the hub to remove it and expose the prop shaft lip
seal. A picture is worth a thousand words, thanks,
Alexandre!

I still am
baffled by my first question. Upon easily separating the
thruster shaft from the clean and well-greased motor, if let
go the whole foot would either fall out the bottom of the
boat or down to the temporary retaining hose clamp (which I
installed about 2" from the very top of the shaft).
Mine didn't. It stopped before reaching the hose clamp,
with 4" of shaft still sticking up. much force,
simultaneous from me above and the diver below, was required
to get the shaft to go the remaining 4" to come out the
bottom of the boat. I am worried that during re-assembly the
shaft will again become stuck, leaving the tape between the
special tool and the shaft underwater for an extended
time.

Thanks very much for
your help,
