Just picked my boat up, 2021 22SVSR with SPS and 150 Mercury 4 stroke. Prop is an Enertia 15.3 x 14. WOT I am running 5870 RPM with 5800 being listed as Max. Called Mercury and they agree it should not be over 5800. My Dealer is great to work with and super helpful, he only put a 14 on based on the Bennington chart. He is open to replacing with a 15P. What's everyone's thoughts please?
