The engine has come out of a lifeboat bought from a firm in dorset I think they sourse them from india where they break ships They check em out service and run them so they are supposedly good and low hours It starts straight away no smoke My thoughts on the vibes are because the original engine bearers were too far apart i extended the brackets So the rubber mflex mount is about five inches from the block instead of about two I suspect this may give the engine more flex than it needs I will try solid mounts next
