I have a bass tracker pro crappie 175 with a 2015 20 HP mercury motor. The boat is used mainly in restricted HP lakes. The motor has a 10P alum. prop. Recommended rpm for this motor is 5400 to 6100 rpm. I am getting 5000 to 5100 rpm. Top speed is 14 mph based on GPS. The trim is set at the next to last hole. I also installed a Hydro foil SE200 on the motor which seems to help some to get stern up. How can I improve performance and speed to go faster and also get to the recommended factory rpm. Here is a video of my boat. Seems like the bow is too high. Located on YouTube .https://youtu.be/a56RDCQcfu4 Would a 4 blade prop help? What pitch?

a four blade could help. every boat is different. last trim hole with the motor trimmed in or up? a smaller pitch would give more rpm but maybe not a faster speed. your trim will change with prop as well. there are a few places that allow you to try a prop before purchasing them. good luck finding the best prop can take a lot of trail and error.
