any good ideas for some form of glue/adhesive that can be applied underwater,  will be short term fix over xmas to glue a piece of rubber onto fibreglass, save me a separate haulout just to do this dry.

What is it exactly that you are trying to glue on and why?

You are not going to get an underwater glue that will adhere to Rubber. Not that i know of anyway. Perhaps talk to one of the Glue selling experts.
However, I do know of a flexible kind of product similar to rubber that is like a really thick (maybe 2mm thick) adhesive tape that will adhere underwater. It is used to seal leaks and comes in a really large size. Not sure who sells it, but I have seen it on TV, so assume it will be Bunnings or Mega10. Always thought I should get some of that, but never got around to it.

I havent seen this stuff for years but it was impressive!

Salesman applied a bead of sealant to a piece of polished stainless steel (that i gave to him from our stocks) while it was under a running cold water tap! 

we used it in wet industrial applications with good results.

No relationship at all...

Seal Once is not an Adhesive though. It will have enough strength to hold something not under any load, but under a bit of load it will pull apart.

Kneed it will not adhere to Rubber. There are many Epoxy Putties that will stick and harden underwater, but they are too rigid once hard to be able to adhere well to rubber.

it is a corner of my saildrive rubber, not mission critical but would like to stick it back to the hull for the break,  no time available on the heard stand, but i am up for a half hour next week so i though dry it up as much as possible and put something on that will set underwater.  Only has to last a month then I can do it properly

If there is water getting in your sail drive rubber would be wise to sort it properly.Could be very expensive to leave it

He’s talking about the rubber boot prevents growth on the upper leg
For what you want Craig I’d say any wet area sealant would do the job

Be aware that no sealant is ever going to cure underwater. So what used is going to need to cure quickly before it goes back in

3M 5200 will cure underwater as its moisture activated.

Good luck on getting it to stick though.

I've read of  people doing thru hulls with it in the water.

Can't you get on the grid and dry area before applying?
