I have a 2017 Tracker Pro 190tx with a 115 Pro Xs motor that start to porpoise around ~5300 rpms with a single rider. The speed is usually around ~46 MPH GPS (52 by gauge) and I have the stock 21 pitch black max 3 blade prop. I have had this boat around 6000 rpm with two riders at around the same speed as above. My motor is still in the factory mount holes which is in the lowest position. Do other users experience this? If I trim down the boat runs smooth as silk but the motor still has some torque left. I'm not to concerned about hole shot but just the stability at top end. I have read alot of people have went with the X7 prop and lowered their pitch with good results.
