Plastic Prop.
Frank:I have one of their Plastic/composite props. It has been fine. I have got probably 300-400 miles on it.I am in fresh water, so build up has NOT been any problem. It appears to give me better control in forward and reverse but I have NO benchmarks to tell you that I now go .5 kts faster......... I have nothing negative to report.They can be repitched at the factory if needed. I am using mine on a 2GM20F on a 1985 H'31.
