thull Posted October 18, 2017 Report Share Posted October 18, 2017 Is there a minimum and/or maximum for this distance? Thanks Quote Link to comment Share on other sites More sharing options...
Ken_Potts Posted October 18, 2017 Report Share Posted October 18, 2017 You'll have to make a compromise there. The gap between the prop hub and the shaft bearing should be as small as possible to reduce the bending loads on the shaft but there should be clearance between the propeller blades and the skeg. The closer the propeller blades are to the skeg (or the hull or the rudder) the more vibration will be felt. In "Propeller Handbook" Dave Gerr suggests a minimum of 0.3x the prop diameter between the blades and the skeg, but that may be too much distance between the prop hub and the bearing. I bet PAR will give you a much more definitive (and helpful) answer than I did. Quote Link to comment Share on other sites More sharing options...
