Humm..... I gained approx 8 mph with 50 extra hp....so let's just figure 15 mph per 100 hp.
With 300hp, I believe Scepter runs about 50mph. Since the rule of " diminishing returns " kicks in, speed increase per 100 hp will yield less.... but, fair enough even at 10mph per 100, 80mph seems possible !! ( assuming of course the hull can handle)
In sailboating, there's a term called " hull speed" meaning no matter how hard the wind blows, that hull will only reach approx X mph.
Seems the older 23 was a hull capable of speed.
