The engine ive on is a 2010 honda 20hp bf20. I was wondering if it would benefit from a hi thrust propellor as I think it might make docking in marina easier. Is this right? I was thinkin about an outboard rudder but was told not to put one on by someone as they catch weed and as im on lough erne im goin between river and Lake and only really need it for mooring. Does hi thrust give better fuel return? At the moment average speed is 5 k ots max about 7 or 8.
