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.
