Hi, yes she was advertised as having a lister sr3 engine dismantled but it appears that during her time on the little ouse parts slowly disappeared from the engine and when we bought her all that was left was the bottom end of an sr3 engine with a hydrolic gear box. We have since sourced all the parts from a donor engine and a very good friend of ours has re built the sr3 which looks and runs amazingly even after being under water for a few years! Will try to post some photos later on. We are new to this sorry, what is the Fens? I do land dwelling properties usually, this is my first boat.
