[Public-list] Caulking lazerette/packing gland nut

[EddieDiver at aol.com]

Roger; I have never heard of "self-leveling" silicone. There are  
self-leveling polyurethanes and epoxies for floors and sidewalks. If the  silicone is a 
one-part, right out of the tube or can, it cures from the exposed  surfaces in. 
As you have discovered, it will skin over, dry to the  touch, quite quickly 
but 2 inches would take a long time to cure  completely. A two component 
silicone (or polyurethane or epoxy) comes in 2  containers and must be mixed. One of 
the 2 components is a catalyst and it cures  almost too quick.
 
Many of the one-part sealants cure in the presence of moisture. If the  
caulking is performed on a dry day, it will take longer to cure. Do the  directions 
suggest spraying with water?
 
I am in the process of drilling new larger drainage holes in my lazerettes.  
I am also cutting out a larger access port in the port lazerette, while the 
boat  is in the water. Three people, taking turns, drilling a series of 
connecting  holes with a battery-powered spade bit drill. 
 
Looking at my prop shaft packing gland thru the cockpit sole hole or the  
small port in the lazerette, I can not get close enough to see a separate  
locking nut on the packing gland. Every one I've seenand all of the Alberg links  
show a separate locking nut. Do you have one?
