no. These have a sort of diaphram that opens up when the pressure inside the boat well is greater than the outside water pressure. Stop teasing me you bastard, you know what I mean...............

I had one of them. It's now installed in the local land-fill.

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.
Cheers mark, that sounds like a good idea - if its any consilation with a boat as small as mine its a pig of a job as theres no room, I sweating like a pig inhaling burning wood/fibreglass fumes,deafened by drilling and fastly catching the tourettes syndrome -

the glass needed a bit of poking, ply was thick, bone dry, and made of many intact layers thanks all for your replies

A large radius on the inside face of the transom will increase the flow considerably. And I mean a lot!
