Excellent. Thank you. It has been suggested that with a small prop there is no point in my getting a larger (say 130hp) engine. But would the extra hp be useful for braking, turning etc? > From what you say there is plenty of clearance above the blade as for >below if you are worried about clearance you could fit a drop skeg >(provided the waterways are deep enough) which would involve very little >modification. Loads of room above the prop. Most of the waterways we're likely to go on have enough water for our 4' draft but low summer levels could be a problem. The other drawback to a drop skeg would be when dry-docking, although we might be OK if we lined it up properly (there's really only one dry dock we can use). The other thought I had was to replace the current box-section skeg with a thinner bar, supplemented by another bar well above the prop to help hold the rudder in position. Incidentally there are pics of the prop etc amongst other things on http://www.pbase.com/bjg/big_iron bjg
