First post, great site. Hello all!


Take looksie at these pic.s.
I feel the need to replace the four drain thru hulls. These two pic.s are of the floor drains. Any advice on re installation of new thru hulls? What holds them tight to the hull? Adhesive only it appears. There is NO ROOM for the backing nut!? The pic. with the nut is an example of the other two.

The radius where the floor meets the transom is mighty close to where the thru hull comes in... little to no clearance for the backing nut...

Advice and Help on how I can "set" these in to stay ... .

Have a safe weekend - Chris

What size is this Conquest for clarification?
Size of the model may or may not make a difference but should be included for reference.

(please read guideline #3 at the top of this page)

I have a related question, sort of. For things that go through the hull, like drains, bow eyes, stern lifting rings, etc ... when they are fastened and tightened, we're compressing two sets of fiberglass (inner and outer hull) and the foam that's between them. In the above example of inner "nuts" not fitting, could it be that the distance between inner and outer hull has increased for some reason (foam swelling, warpage of one or the other hull, or etc)???? The reason I ask is that my brand new boat after only about a dozen launch/retrieve cycles had a loose nut on the bow eye. I could get no proper answer on how tight to tighten it, and I am not completely certain what that assembly screws through (being a bow eye, I am guessing it is the heaviest phenolic spread over a large area, but the Whaler manual does not describe that area). Was my loose nut caused by a "shrinkage" of the hull in that area? Is the OP's inability to put his nut on the drain due to "expansion" of the hull in his boat?
