I have a 25hp etec with cmc tilt and trim on a lt25 gheenoe. Factory prop is a 10.3x12 pitch and it had too high of an rpm. I put a tach on the boat and replaced it with a Powertech SRA 12 10" diameter. I am looking for a larger diameter because with the sra I am spinning 6200-6300 rpms!!! Way too much!!! Any suggestions? Looking at a Turning Point Express 10 1/8" 14p prop?
