I am looking for some advice on prop recommendations for my 2018 Crestliner 1750 Bass Hawk with a 115 Mercury Pro XS. I am having serious issues with hole shot and then porpoising. With the boat loaded down, 2 teenagers and myself, getting on plane is a struggle and then once on plane, I can barely touch the trim and we start to porpoise. This starts to happen around 5100-5300 RPM right when the engine starts to sound good like it is not struggle any longer.
My merc has 2.07:1 gear ratio with a 12.7” 19P four blade Spitfire stainless steel prop. Thoughts, suggestions, or questions for more info to provide some ideas?
