I was contacted by Marc about the skeg on his engine. I didn\'t have the answer but asked here http://www.castlemarine.co.uk/. It is just down the road from where I live. The owner, Harry, is really helpfull. I have used them for some time for prop repairs, they have always charged in the region if £35 and the prop comes back like new. Usefull link to have if you ding the prop or skeg on your engine, unless you have somewhere more local.
