I think I am propped just about as well as I can be for my hull/F115 combo, and my engine is raised off the transom. So taking the prop/engine height out of the equation for getting better performance I am wondering if there are any engine mods available to squeeze a bit more out of the engine. As I understand it, or at least I have heard, the F115 power output is actually around 105-110hp. Probably a silly endeavor but I just thought I would pose the question. My hull is rated for 115 so going to a 150 is not an option.
