how much power do I needed?

I run an 88spl on my 19 BR which is the same boat just measured from a differant place. I get a 30mph cruise out her with two guys and loaded for fishing. I have a hard top with enclosure and outriggers. My outboard guy told me 75% 100% of the time is the best for an outboard so with the 88 75% is my cruise and I can run it in allmost every sea and not pound the boat and I'm not getting in everyones way either. As the picture shows she's fast enought to bend the antennas
