[Alberg30] RE: Merriman winches and dripless shaft seal

[Hugh Freebairn]

Ross,

Did you install the green stuffing box material with the boat in the water?  
Would it be possible to do so?  I have used the dripless mechanical shaft 
seals for over 7 years now on other boats besides my A30 and I have been 
very happy with them.  I had to have the boat out to install them and pull 
the shaft part way out of the engine coupling to get them on.
