What propeller for a 23' Sceptre?

[breadandbobbers]

I have a 1978 23' Sceptre. I had a Armstrong bracket installed on the boat recently and put a brand new 225 hp Opti on it. The prop before did well with the boat, a 14P Mercury Mirage. However now the propeller seems to not have enough pitch and gives too much bow rise--before the boat had the bracket the boat was definitely bow heavy and the propeller did well, not it does not. The boat maxes out at 6400-6500 rpms currently, and max rev on the opti is 6750

anyways does anyone have a similar setup or have any recomendations? I use the boat for fishing offshore so I am looking for something that will perform well in the open water.
