Re: propeller suggestions
Some other variables need to be aired.
Which boat make/model is it? Displacement(weight)?
Does it have a prop in an aperture before the rudder or is it a free standing prop?
With a strut or no strut?
You'd likely see a performance improvement with either the Indigo 3 blade prop designed for the A4 or a Campbell Sailor prop as mentioned.
The hull shape and design of your boat does make a difference though.
