Anyone know where i can find an owners manual for this boat, to buy or to download, i would like to learn more about it and its history 
Afraid you won't find one as there is no such thing. Boat builders (especially small back-shed firms) until recently never produced any sort of manual. Best to ask specific questions and build up your own portfolio.
The Concorde range of speedboats were built by Dudley Marine in Milford Haven during the seventies and eighties. I used to have a Concorde Florida which was virtually identical to the fiesta although a little larger at 17'6". I think towards the end of the eighties some of the moulds were rented out to someone on the south coast, but don't know much more than that. The owner of Dudley Marine was Lyn Dudley and his wife, they also owned a fishing/watersports shop in Milford Haven. IIRC Lyn's main job was a woodwork teacher at a local comprehensive school. I'm pretty sure there was never a manual for these boats.

We had a Merc 100 on it and it went like stink, the hulls are quite narrow and the handling on ours was great but at full throttle there was next to no boat in the water so she used to start to hop and move about a bit. The boats were built for speed more than stability although we used ours mainly for skiing.
Dudley Marine also ran powerboat trips out of Saundersfoot during the eighties using a one off 20ft version, coincidentally it's just been sold on ebay (item 120613228273). Ours, like yours was one of the later models as the earlier ones didn't have the stainless rail behind the screen. Be careful with that, the boats are made to be thrown around at speed but a good wave over the bow and the screen tends to break against the stainless as it's not able to flex fully - we went through 3 screens on ours!
