If it's a Humber and you need the transom modified, fit a lighting pole and it will modify itself...

What shape is your transom? My Destroyer transom was lower in the middle where the main sat on it, but I fitted a long shaft aux straight on and it worked fine with no modification at all to the fibreglass?

A Boat is a hole in the water, surrounded by fibreglass, into which you throw money...

If the prop is barely below the surface in a calm sea you will make no headway at all in a sea. Try it and see if you need to but surely it's obvious no? Varnish is impermeable and when covered from the effects of UV by a sikaflex filled channel it's not going to let water in really is it? Complicate it if you really must but it's not rocket science........

Bogmonster - It`s an ocean pro. The transom is curved and high either side of the main motor. It would have needed trimming either way to take my aux.
Thanks for comments everyone. I took a saw to the transom of my newly purchased rib at the weekend. Following Pikey Daves advice i repaired the exposed ply using west systems epoxy and biaxial mat. Not sure how many layers i should be using but i`m on 3? Shouldn`t matter really as its more to seal the exposed upper edge rather than anything structural.
Will upload step by step pics when i get chance.
