2004 Martinique. The light assembly is leaking, bead of silicone under the lens on interior of tub was disentigrated. I was going to remove, try to find an o-ring(assuming there is one back there) re-silicone and replace. I can't figure out how to get to the nut on the back of the assembly. it looks to be basically a 4" male pvc adapter with a locknut that tightens it to the wall of the spa. It is inside of an approx. 6" heavy cardboard tube. I can't reach it to get a grip on the nut to see if it loosens. Is there a special tool to remove or should I be able to remove it from the inside of the tub itself?
