[C320-list] Engine seacock and no water out the exhaust - 27 hp, 3G Yanmar

[tharrison at innovations-plus.com]

I do not think that would be possible Graeme. I think the screw just passes
by the seacock plastic and screws into the fiberglass bottom of the boat. By
packing the fiberglass into the screw hole I would be just filling in and
not they are telling me just a little epoxy is required. 

If the fiberglass does not adhere to the seacock would be a good thing. If
it ever needed to be replaced!

The danger is that the epoxy "plug" will not adhere to the plastic cavity as
this sort of oily polythene type of plastic is not good for that Is there
any way you can enlarge the old screw hole at the deepest point so that the
epoxy plug is bigger at the bottom and thus retained by the surrounding
material?
Personally I'd drill out the old hole slightly larger than the outside
diameter of the screw that fits in it, then maybe use a smaller drill to try
and go at a cross angle to make the bottom a bit bigger before filling as
you describe But it's just my thought! I'm probably over engineering it!

You never know.
