Which Propellers

considering fitting polycarvbonate props with adjustable pitch and relaceable blades.i.e manufactured by Propulse/Pirannah, onto my 585 ribcraft powered by 2 x 60 hp Mariner 2 strokes has anyone any experience of these and are they to be recommended. I'm also considering going over to four blades as opposed to three to gain better thrust and mid range cruising/lower planing speeds. any feedback/experiences would be appreciated

I used the Piranha for a while. It held the water well but it gave a reduced top speed. I tried various pitches but I felt the extra drag of the thick section blades plus the 4th blade limited its performance. It was fitted to an OMC 150hp. Also, they were not very accurately made and I had to remachine the taper.
