I have had my Catalina 27 now for about 10 years and need to replace my outboard. For some strange reason it seems that hauling this 9.9 hp motor off and on seems to be getting harder and harder and so was wondering if a smaller motor like maybe a 6 hp would still propel the boat well enough? I only sail the lake so currents wouldn't be a factor but I would still like to be able to manuver the boat around too. Anybody know for sure? Appreciate any and all advice or suggestions.
