I have in additional to my sailboat a conventional powerboat with 90 ho Johnson outboard. I run it with a 4 blade carbon fiber prop which I love. It's a comp-prop which are not made anymore. It is extreamly rugged and works very nicely.

Check this guy living on a solar powered catamaran tied up to his own island in Panama. This is the prop for his solar powered runabout.On Wednesday, March 2, 2016 3:33 PM, "'Jason (Electric Boats) Taylor' jt.yahoo@jtaylor.ca [electricboats]" <electricboats@yahoogroups.com> wrote:
Carbon fibre's strength comes from the weave, not just the fibres or resin themselves. The way the resin and fibre is built up will likely lend itself to poorer shear performance and as a prop loads up, it will certainly try to tear itself apart. How would polycarbonate resin impregnated Carbon fibre have done? Could the tool-path have been altered to impart different properties to the prop? There are so many variables involved.Hey thanks for that, Jason. Most interesting. Surprised about the carbon fiber not holding up. I would have put my money on that one.
