Just got this boat a week ago. My last boat was a Ranger RT178c and I didn't have porpoising this often. If I did I trimmed down a small amount and it stopped. I'm mostly noticing it when I slow down. Before taking a wake or right after I come out of a turn. Is it that I just need to learn how to trim it correctly or is it most likely loaded incorrectly? If I trim back down it will stop. I've not had a boat this big or fast so it's different for sure. The trim gauge stays toward the lower half of the gauge making it difficult to see how much it's trimmed.
