Hey Guys it has taken me 17 years but I finally bought the prettiest boat I have ever seen or fished out. It is a 1991 Basscat Pantera II DC with a 1991 Mercury 175 XRI standard jackplate and a Mercury High 5 prop. I have been told the boat will perform better with a different prop but the previous owner couldnt remember what. I am a big guy and so it my fishing buddy, combined weight plus gear will be between 600 to 700 lbs. With a fully loaded boat what do you suggest for top speed and what mph can I expect? Also would like to here comments on other props and there benefits vs. top speed. Thanks for any and all help. jmd Centerton, Arkansas
