I bought a used 2017 4 stroke ProXS 115 for my aluminum bass boat. When I had my 115 2 stoke on my 6 inch CMC JP I would top out at a little more than 47 mph. With my 4S 115 I am only getting 39mph at best with the same load as I had with the 2S. I’m trying to figure out if I should raise or lower my JP to improve my performance. The JP position was never changed when the new motor was installed. Any ideas as to the direction I should go on the JP?
