I have a 1988 Larson International Series 256 CC/Cuddy cabin which was originally powered with an OMC Seadrive motor. It has been converted to an Armstrong bracket with twin 200hp Johnson Oceanrunners. I'm thinking about repowering with a single outboard and would like to know what the horsepower was on its original OMC Seadrive. Does anyone out there know? I do not want an underpowered boat and am concerned that a single 250 hp outboard may not be enough. Thanks for your help.
