My RV-3 came with a Sensenich 68x86 propeller, trimmed to 66". I want to replace it for better performance. With the Sensenich, I was getting about 150 mph or less at 2700 rpm, but I don't know what kind of performance to expect. The guy I bought it from claimed 175 mph. Props Inc recommends 68x68 for an O-320. Can anybody give me any recommendations? Thanks.
