I have a 2019 2060 and had the same issues, RPM’s are 5700-5800 at 55-56 mph loaded with gear and ~1/2 tank of fuel, could get more rpm’s but it’s just prop slip between 5800-6000. I tried a 19.5 and 19 pitch Bravo I LT’s and both improved the porpoising as well as hole shot and mid range..only issue was neither prop wanted to spin over 5500-5600 rpm’s but did it at 55 mph. I tried multiple engine heights with all props, ended up raising the motor about 1” from factory which also tamed the poroising while keeping the rpm’s closer to 5800 on the swsii prop. I ended up selling both of those props and going back to the SWSII with 4 dots showing on the manual jackplate. I also put a series 27 cranking battery in the front drivers side storage bin for my front graph (would always turn off when cranking motor). The added weight up front helped cut down on porpoising, still have to set the trim tab under the kicker on 1 bar to keep her level but it’s not as noticeable as it was before putting the battery up front. Learning to use the trim tabs on this boat is key, it is an extra step but they make a BIG difference in ride, it’s now 2nd nature before taking off i’ll put them on 3 or 4 bars then once at 35-40 mph up to just one on the port side and not beginning to trim the motor until about that same speed.
