More elephants trunk stuff

Just installed mine as it didnt have one at all, I burnt out an old drill doing the whole and it took bloomin ages, the revs of the drill its slef kept slowing down the pressure to cut through was on, it nearly stopped a few times and bit back at me at the handle end!!

the 11cm drill bit itself was only just deep enough to get through all the layers, I've now siliconed it all up hopefully it'll work a treat if I need it -
space is a bit limited on the transom now - what shall I seal the new hole with from the inside as I guess when it gets wet it might go rotten? I've used silkaflex at the moment, is there anything better I should be using?

silkaflex is good if done right
One thing though itís a good idea to have the closing string fitted over the top of the transom and on a quick cleat this makes it easy to see if the trunk is up or down and to operate. Des

Might be a good idea to epoxy/glass the cut edges first.

Olly

It would be best to seal the hole with GRP as Jono said.
You can get 50mm wide woven tape which is good for this sort of job. When that has gone off seal that with gel coat.

How easily did the glass come off the ply core when you cut the hole?
It may be delaminating if it fell off easily.
Was the ply wet? That might explain why the cutter was binding.
I hate those multi-size hole cutters. I am impressed you got anywhere with that one.

It's this bit... When you lower it into the water, forward motion of the boat enables water to be drawn from the inside, by differential water pressure, in reasonable quantities to empty a partially flooded hull. As it's "floppy" it kind of acts as a none return valve ... does that help?

Took me a moment to work out what that was.
