While you may be under propped, it's not as simple as just adding more pitch. The boat will most likely not get up on plane with that motor. The object is to pitch the prop so that it turns rated RPM at wide open throttle. The maximum speed for that boat with that motor might only be 8 to 9 knots. Changing the pitch to 25 might be too much. This is an area where it's best to talk with a good prop shop that has experience with displacement hull trawlers.
