I've been trying to find online ( Google ).. Explanation on horsepower/performance and how it works in a jet boat.. If I have a 386 hp motor and I decide to go with a 450 hp motor.. I'm to believe that, all I gain is quicker out of the hole and maybe a little more top end speed.. That fact is the pump and impeller will still be turning at the same rpms ( may it be 4,000/4,500 rpms ).. What are the benefits for increasing horsepower.. Less strain on motor to achieve rpms?? Please, anyone who can explain.. Thank You
