I am learning more and more how to drive my boat(2022 F195/200 Optimax). I have read that many people have been able to run in the low 70s but, I have not been able to do that. Using the trim and hydraulic jack plate I finally did it. No chin walk and no control issues at all. I am finally getting the hang of this :-). Still got a few hundred more RPMs I am happy with what I got.
