Q:

How close to the bottom of the boat can blade tips run and what is the required aperture clearance?
A: The clearance between the propeller tips and the hull should be at least 1/6 to 1/7 the propeller diameter. Clearance is equally important along the forward edges of the blade where they swing in line with the deadwood and should not be less than 1/12 of the diameter.
