I have a 1981, 25' 251 Catalina Express with a 305K (225hp) engine. The max speed I seem to be able to get from her is about 12.5knt/hr. On her 1" shaft, I have a 13x10 prop which seems to be what the engine spec calls for. But I keep thinking, I should be able to get more speed from her then that. Does anyone have a similar experience or is using a different size wheel? Thanks for any help / advice one might offer.
