Re: Stuffing box drainage path

 Guys AND Gals,    ( Gotta get that right as the admiral on Pen Azen is female),

I share Danny's surprise, but maybe we are just lucky.  We have had water through the bow thruster but only when we have waited too long between changing the foam seals. We've just been through a big bash to windward when we had to motor sail into heavy seas---not a drop came in.  To be fair, we rarely use our bow thruster, as once we are afloat we prefer to live at anchor.

 As to the rudder stuffing box, I will have to leave you to guess if a drop has ever  come through in 19 years and nearly 65,000 miles, because my admiral is really superstitious and if I spelt out the answer she would hit me over the head with the anchor for tempting fate.

Hi guys

 I am staggered at the equanimity with which you accept water ingress. At the first sign of seepage around either the bow thruster or the rudder shaft I fix it. If there is a biannual replacement of the thruster foam seals  an at sea change of the upper seal does it and likewise the stuffing box is a easy at sea fix. Regular maintenance of both reduces the chance of needing to do it at sea.

I think Cream Puff was retrofitted. We have a pump in the area that collects water from the leaking bow-thruster area connected to a sensor and alarm. When the sensor kicks in the alarm sounds and the pump automatically pumps the water into the forward head shower pan that obviously makes its way to the bilge. The alarm can be silenced for those trips when the bow thruster seriously need new seals.


I particularly like this set up because no modification was made to the watertight bulkhead.

Can that change be retrofitted to a 1999 SM?

Late model SM Bow Thrusters do capture any sea water seepage and drain that to the gray water bilge. This change was done sometime in 2003.

My bow thruster will not leak to an exit to the bilge.  It will be stopped at the forward head where it must be dealt with manually.  If you have a situation where seawater has a direct path to the the engine room bilge (other than the anchor locker), I would say that it's not original (or I didn't read your statement correctly). ..  

Having a water alarm next to the rudder quadrant is a great idea.  I just have to hoist the bed once a month while we're parked, once a day while we are underway.
