Internal Alu Mast sealing.

[Brian Duff]

follow the selden example.

pull the rig, insert a dam that is made of 3/4" plastic/foam with a short (12") conduit in the center of it. Slide it coated in sealant up the rig to just above the mast boot. Rivet it in place. make a few 3/8" holes around the mast just above the dam, sometimes there is a hand access hole here but i don't belive on selden rigs there is. seal above the dam with sealant applied via a copper tube worked through these small holes. The wiring inside the rig either goes down with a drip loop, up and into the center conduit, or outside of the rig, at this point.

that help?

the copper tube is the real trick, good luck!
